Research Interests

Efficient Contact Formulations for Adhesion Between Deformable Solids

Adhesion can be observed on biological surfaces such as insect and lizard feet, as well as artificial surfaces like self-adhering foils. The mechanical modeling and simulation of adhesion mechanisms poses numerical challenges due to the non-linearity, complexity and potential instability of such problems.
This research aims to develop efficient finite element and contact formulations to simulate adhesion between deformable solids undergoing large deformations. The bodies are described by a continuum mechanical model, the van der Waals adhesion by the Lennard-Jones potential. Special attention is given to the deformation of the contact surface, the contact pressure and the tensile adhesive forces. Standard finite element methods rely on highly refined meshes to yield accurate results in the contact interface, resulting in high computational costs. The development of methods to obtain accurate results efficiently (i.e. without increasing the computational cost dramatically) is therefor desirable. To take advantage of modern computer architectures, parallelization of the code is considered.
