A short journey into the realm of numerical methods for contact in elastodynamics
, 2023 MasterThe main objective of these lecture notes is to provide basic notions about the finite element discretization of frictionless contact in elastodynamics, to point out where the main problems may occur, and what are the possible remedies.

Implementation of Space-Time Finite Element Formulation in Elastodynamics [PDF]
, 2016 Elastodynamics is an academic field that is involved in solving problems related to the field of wave propagation in continuous solid medium. Finite element methods have long been an accepted way of solving elastodynamics problems in the spatial ...

Logarithmic Convexity, Continuous Dependence and Uniqueness in Elastodynamics with Higher Gradients [PDF]
We investigate Hölder continuous dependence in theories of linear elastodynamics, assuming the elastic coefficients are not sign-definite. This is important with modern products such as auxetic materials where Poisson’s ratio may be negative.

Riemann Problem for a limiting system in elastodynamics
Electronic Journal of Differential Equations, 2014 This article concerns the resolution of the Riemann problem for a 2x2 system in nonconservative form exhibiting parabolic degeneracy. The system can be perceived as the limiting equation (depending on a parameter tending to 0) of a 2x2 strictly ...

Exponential time propagators for elastodynamics
We propose a computationally efficient and systematically convergent approach for elastodynamics simulations. We recast the second-order dynamical equation of elastodynamics into an equivalent first-order system of coupled equations, so as to express the

Generalized sub-region mixed and hybrid variational principles in nonlinear elastodynamics
, 1990 In this paper, the Hu-Washizu generalized variational principle is extended to nonlinear elastodynamics with five independent fields. The two kinds of framework of functional, the potential energy and complementary energy expressions containing the ...

On the hyperbolicity condition in linear elasticity
Le Matematiche, 1991 This talk, which is mainly expository and based on [2-5], discusses the hyperbolicity conditions in linear elastodynamics. Particular emphasis is devoted to the key role it plays in the uniqueness questions associated with the mixed boundary-initial ...

Root finding method for problems of elastodynamics
Computer Assisted Methods in Engineering and Science, 2017 This paper presents a simple and efficient method for finding complex roots of dispersion equations occurring in many problems of elastodynamics. The method is characterized by high accuracy in root finding and absence of restrictions on function ...
