Space-Time Finite Element Methods for Dynamic Frictional Contact Problems

Space-time finite element methods for dynamic frictional contact problems are discussed in this article. The discretization scheme is based on a mixed formulation of the continuous problem, where the Lagrange multipliers represent the contact and frictional stresses. Using piecewise d-linear and globally continuous basis functions in space and time to construct the trial space for the displacem...

Using the Finite Element Analysis Method to Study the 3-point Bending Test for the Characterization of the Adherence

An elastic finite element analysis was conducted to evaluate the stress distribution in the initiation zone of the adhesive rupture during the 3-point bending test. This test is used to measure the adherence between a polyepoxy adhesive and aluminum alloy with different surface treatments. The purpose is to compare, in the high stress concentration areas, the stress fields calculated using fini...

On Finite Element Uniqueness Studies for Coulomb’s Frictional Contact Model

We are interested in the finite element approximation of Coulomb’s frictional unilateral contact problem in linear elasticity. Using a mixed finite element method and an appropriate regularization, it becomes possible to prove existence and uniqueness when the friction coefficient is less than Cε| log(h)|−1, where h and ε denote the discretization and regularization parameters, respectively. Th...
