The Fourth Australasian Conference on Computational Mechanics

University of Tasmania, Sandy Bay Campus | 28th – 29th November 2019 (pre-conference workshop on 27th Nov)

University of Tasmania is proud to host the 4th Australasian Conference on Computational Mechanics.

The conference will be held at our Sandy Bay Campus within the state-of-the-art Harvard Lecture Theatre, Centenary Lecture Theatre and Engineering Design Centre in the Centenary and Engineering Buildings.

Welcome Message

Dear ACCM Members, Friends and Colleagues,

On behalf of the organising committee and as the conference chair, we would like to welcome you to the 4th Australasian Conference on Computational Mechanics (ACCM-4) held in Hobart, Australia from 28-29 November 2019 (with a pre-conference workshop on 27 Nov).

The Australasian Association for Computational Mechanics (AACM) facilitates the organisation of this premier biennial conference. The conference aims to provide an international forum for researchers, industry practitioners, engineers and postgraduate scholars to promote, exchange and disseminate recent findings on contemporary and wide-ranging topics in Computational Mechanics.

Computational Mechanics is a fundamental subject of engineering science. It underpins all of the primary engineering disciplines, including Civil, Mechanical, and Materials Engineering. Computational Mechanics addresses a broad range of areas, from conventional structural and mechanical designs, failure analysis, dynamic and vibration analysis, and fluid mechanics to cutting-edge computational mechanics, nano-micro mechanics, multiscale mechanics, coupled multiphysics problems and novel materials. This is truly reflected in the variety of fields featured in the conference topics. One key aim of ACCM is to retain and engage high-quality graduate students in Computational Mechanics research. ACCM aims to nurture the talent of young researchers through its best paper awards.

The ACCM series started in 2013 with the ACCM-1, ACCM-2 and ACCM-3 held in Sydney, Brisbane and Geelong, respectively. The ACCM conference has become a flagship activity of AACM and will be regularly organised. ACCM will accommodate presentations on a wide range of topics to facilitate the interdisciplinary exchange of ideas in science, engineering and allied disciplines, and helps to foster collaborations.

The ACCM conference is unique in that it showcases the current trends and research developments in Computational Mechanics in the Australasian region and its relationship to national and regional priorities. The extended abstracts to be presented at ACCM-4 will address many grand challenges in modern engineering. The extended abstracts to be presented at ACCM-4 will be peer-reviewed by expert reviewers including members of the National Scientific and Local Organising Committees for ACCM-4. The topics of these extended abstracts will range from nano- to macro-mechanics of materials, dynamics, sustainable manufacturing, biomechanics and computational mechanics.

Finally, we invite you to participate in the ACCM-4 conference, and hope you will have a wonderful and richly rewarding conference experience in Hobart, Australia. We look forward to your participation at this and continued engagement at future ACCM conferences.

Computational Slope Stability Analysis

Slope stability analysis remains a central activity for geotechnical practitioners and a continued area of interest and research for academics. A wide range of methodologies for slope stability analysis have been developed, ranging from Taylor’s charts from the 1930’s to state-of-art random finite element methods for probabilistic analysis. The lecture describes two simple slope stability analyses that can lead to unconservative (unsafe) solutions. Firstly, a classical problem solved by Taylor is revisited using (i) simple optimization, (ii) elastic-plastic finite elements with strength reduction and (iii) upper- and lower-bound finite element limit analysis. The results show the benefits of the finite element approaches, especially as the slope becomes relatively flat where the simple approach starts to overestimate the factor of safety. Secondly, a probabilistic slope stability analysis is performed using (i) a simple analytical approach and (ii) the random finite element method (RFEM). For the case considered, the analytical approach is shown to underestimate the probability of failure, by failing to account for spatial variability in the form of a correlation length.

Simulating Fluid Flow in Complex Geometries on Structured Meshes

This presentation will give a comparison of three approaches commonly used to model fluid flow in geometrically complex domains: the Cut Cell Method, Immersed Boundary Method and Curvilinear Coordinate Method. These approaches are discussed with reference to implementations within our CFD code -- PUFFIN. In the Cut Cell Method, a Cartesian mesh is used and complex boundaries are defined by truncating any computational cells intersected by the boundary. This leads to extra terms in the equations for the boundary cells but leaves the equations for the remaining cells in standard Cartesian form. In the Immersed Boundary Method, boundaries are represented through the creation of a set of virtual nodes lying on the boundary surfaces. Forcing terms are added to the equations for cells in the vicinity of the boundaries that drive the solution towards one that satisfies the boundary conditions at the virtual nodes. In the Curvilinear Coordinate Method, the governing equations are solved in a coordinate system that is transformed so that coordinate planes are aligned with the domain boundaries. This last method is mathematically complex, so a brief overview of relevant aspects of the theory of tensor analysis is given before proceeding to a description of our implementation.

Evolutionary Computation in Structural and Geo-mechanics

Evolutionary computation (EC) techniques are a subset of artificial intelligence, but they are slightly different from the classical methods in the sense that the intelligence of EC comes from biological systems. The central theme of this presentation is about EC techniques and their application to structural and geotechnical engineering problems. On this basis, the presentation is divided into two separate sections, including (big) data mining, and global optimisation. First, applied evolutionary computing in structural and geotechnical engineering data mining will be presented, and then their new advances will be mentioned, such as big data mining. After EC introduction, the EC applications for response modelling of a complex structural system under seismic loads will be explained in detail to demonstrate the applicability of these algorithms on a complex civil engineering problem. In the second section, the evolutionary optimisation algorithms and their key applications in the optimisation of complex and nonlinear civil engineering systems will be discussed. EC advantages over the classical optimisation problems and optimisation results of large-scale civil engineering systems using EC will be presented in this part. Some heuristics will be explained which are adaptable with EC and they can significantly improve their results.

My 45 Years’ Journey as a Biomedical (Bloody) Engineer, Including Australian Experience

Throughout my 45 years of research in Japan and Australia, I have participated in three ventricular assist system (VAS) projects. Of the three, two projects reached clinical application and commercialization. However, I had a critical stressful concern during pumping on my first “First in Human (FIH)”. My first FIH was in 1982, and involved a pneumatically-driven VAS at the National Cardiovascular Center, Osaka. The second FIH, in 2005, was with an implantable centrifugal-type VAS (EVAHEART) at Tokyo Women’s Medical University. Both VASs got official government approval for clinical device production in 1991 and 2011, respectively. The third VAS, an Australian project at St. Vincent’s Hospital, received an international patent for the Spiral Vortex pulsatile pump, and prototyped a mass production manufacturing technology. However, although the pump cost was dramatically reduced (90%), it did not achieve commercial success. Based on my experience, I would like to emphasize the importance of obtaining safety and efficacy data. Firstly, engineering analysis by modeling and simulation technology with sophisticated mock circulatory systems and CFD is the most effective approach, in addition to animal experiments. I named this approach: “another EBM; Engineering Based Medicine”. Of course, knowledge of medical regulatory affairs is also required to clear the hurdle of government approval.
