Summary on Grant Application Form |
|
The project is aimed at developing numerical techniques which can be used to analyse micromechanical contact conditions in various processes and components. The procedure will be based on the concept of discrete elements in which separate deformable bodies, which remain in frictional contact, are progressively formed by the fracture of an initial continuum. The combined finite/discrete element approach will be employed to quantify local contact forces at asperity level, monitor the breakdown of asperities under critical loads and simulate the formation of abrasive wear particles.A conventional finite element approach will be initially adopted for the simulation of cold forming operations to provide macroscopic boundary conditions in the contact regions. These data will be transferred to the discrete element model to simulate contact/friction effects at the micromechanical level. This information will finally be employed in the development of improved constitutive laws for contact/friction behaviour for subsequent use in conventional (macroscopic) simulations of cold forming operations.By this approach the fundamental understanding of friction and wear will be enhanced, which will have an impact on better design and optimisation practices in engineering sector such as the metal forming, automotive and aerospace industries.
