Aims: This proposal aims to expand the bidirectional evolutionary structural optimisation (BESO) method for transient mechanical, multiphysical and robotic problems.
Significance: The study will develop new BESO transient algorithms by integrating time-dependent analysis and stepwise design sensitivity in multicriteria and multidisciplinary optimisation.
Expected outcomes: The project will largely broaden the algorithmic scope of BESO and enables it to solve more extensive real-life problems with time-varying nature.
Benefits include a new BESO design framework and computer program, as well as a series of novel designs, potentially being implemented for aerospace, automotive, biomedical, mechanical, civil and mechatronic applications.Read moreRead less
Fundamental research advancing remanufacturing with a 3D printing technique. 3D printing manufactures items directly from a computer model. This project aims to develop a computational tool for applying direct laser metal deposition, a 3D-printing method, to repair metallic components and develop a way to predict the remaining life of the remanufactured components. The tool should optimise use of this printing method and improve the quality of repaired components. The research expects to validat ....Fundamental research advancing remanufacturing with a 3D printing technique. 3D printing manufactures items directly from a computer model. This project aims to develop a computational tool for applying direct laser metal deposition, a 3D-printing method, to repair metallic components and develop a way to predict the remaining life of the remanufactured components. The tool should optimise use of this printing method and improve the quality of repaired components. The research expects to validate the tool for simulating the printing process, provide a better heat treatment during repair, and allow safe prediction of the service life of repaired components. This research should benefit the Australian manufacturing industry and reduce resource use by helping apply this 3D printing method in remanufacturing.Read moreRead less
Fatigue Life Assessment of Structures under Realistic Loading Conditions. The project will develop a new methodology for the assessment of fatigue life of structures subjected to realistic loading conditions. This new methodology is based on recent advances in experimental techniques which make possible, for the first time, the investigation of the crack opening/closure mechanisms and the crack driving force for large numbers of fatigue cycles (>1 million) of variable amplitude, representative o ....Fatigue Life Assessment of Structures under Realistic Loading Conditions. The project will develop a new methodology for the assessment of fatigue life of structures subjected to realistic loading conditions. This new methodology is based on recent advances in experimental techniques which make possible, for the first time, the investigation of the crack opening/closure mechanisms and the crack driving force for large numbers of fatigue cycles (>1 million) of variable amplitude, representative of real-world applications. The project will expand Australia’s knowledge base and research capabilities in structural life prognosis. It will increase the competitiveness of domestic products and industries, fostering international collaborations and leadership of Australia in this strategically important area of research.Read moreRead less

Summary
Data-Driven Design for 3D Printed Materials with Tailored Fracture Response. Fracture is the main source of material failure and may cause serious engineering disasters and even death. This project aims to develop a Data-Driven Design System that intelligently optimizes local materials and architectures for heterogeneous structures with desired fracture response, and enhancing their mechanical fracture properties including stiffness, strength, toughness, and failure displacement. It will open up ....Data-Driven Design for 3D Printed Materials with Tailored Fracture Response. Fracture is the main source of material failure and may cause serious engineering disasters and even death. This project aims to develop a Data-Driven Design System that intelligently optimizes local materials and architectures for heterogeneous structures with desired fracture response, and enhancing their mechanical fracture properties including stiffness, strength, toughness, and failure displacement. It will open up a new and promising research field in mechanics and data-driven science that deals with intractable inverse problems in broad engineering fields. Economic, high-performance, and customized 3D printed structural materials will be generated to benefit national corporations and enterprises and meet the high-end industry needs.Read moreRead less
