Research Summary

DEVELOPMENT OF A METHODOLOGY TO MODEL THE FRACTURE PROCESS OF THE LATTICE STRUCTURES

  • The majority of the research were on the mechanical behaviour of the lattice structures mainly focused on the microstructures and mechanical properties study on the lattice structures to determine the strength of the manufactured parts. However, due to the lack of physical understanding of the deformation process, failure mechanisms and methodologies for fracture process prediction for the lattice structures has not been established. The objective of the proposed study is to develop methodology to model fracture mechanism process of lattice structures and to generate lattice structures while study crack initiation phenomena through finite element analysis and possibly experimented testing.

Past Research

Elasto-Plastic Crack Growth Simulation Using XFEM

  • The fatigue crack growth and creep crack growth modelling is carried out in conjunction with XFEM. The calculation of stress intensity factors for respective mode is done by decomposition of J-integral method and the basis of fracture criterion for crack growth based on critical stress intensity factor is studied theoretically. The nonlinear material is modelled by a class of power law hardening. The fatigue crack growth rate and fatigue life are validated with the experimental results for the compact tension (CT) specimen. Furthermore, creep crack growth is also modelled and results are compared with available literatures
