Plotting Load Paths from Finite Element Stress Results

LB 272

Research at University of New South Wales on procedures for plotting load paths from the stress results of a finite element analysis will be described. Applications will include static and transient solutions with application to frames, plates and three-dimensional elasticity. Design work is increasingly being taken out of the hands of the engineer and performed by numerical design software, leaving the engineer to interpret how the design is meeting its primary goals. The motivation is therefore to provide tools to help design engineers understand how a structure is transferring load from points of application to the supports. Unpublished work on utilizing load paths for topology optimization and application to the design of fiber trajectories in steered fiber composite structures will also be described.  

Don Kelly is an Emeritus Professor at the University of New South Wales, Sydney. He has a Diploma from Imperial College of Science and Technology and a PhD from London University. He held a faculty position at University College of Swansea in the U.K. before taking up his post at the University of New South Wales. His research interests included error estimates for the finite element method and analysis and design of composite structures. He coordinated the contribution from the University of New South Wales to the Cooperative Research Centre for Advanced Composite Structures Ltd that brought together leading Australian aerospace companies, the Defence Science and Technology Organization and universities to solve problems in analysis, design and manufacture of composite structures.   He retired from the University of New South Wales in 2010 and was given the honorary title of Emeritus Professor which gives him access to University facilities and enables him to continue his research interests.  He is also working as a finite element software engineer for the company Strand7 Pty Ltd. At Strand7 he is contributing to the development of new features for the commercial finite element solver being marketed by the company.
