Explicit time-discretisation of elastodynamics with some inelastic processes at small strains
Tomas Roubicek, Christos Panagiotopoulos, Chrysoula Tsogka
The 2-step staggered (also called leap-frog) time discretisation of linear 2nd-order Hamiltonian systems (typically linear elastodynamics in a stress-velocity form) is extended for…
Energy-conserving time-discretisation of abstract dynamic problems with applications in continuum mechanics of solids
Tomas Roubicek, Christos G. Panagiotopoulos
An abstract 2nd-order evolution equation or inclusion is discretised in time in such a way that the energy is conserved at least in qualified cases, typically in the cases when the…
Two adhesive-contact models for quasistatic mixed-mode delamination problems
Christos G. Panagiotopoulos, Vladislav Mantic, Tomas Roubicek
Two models for quasistatic adhesive unilateral contact delaminating in mixed fracture mode, i.e. distinguishing the less-dissipative Mode I (opening) from the more-dissipative Mode…
Local-solution approach to quasistatic rate-independent mixed-mode delamination
Tomas Roubicek, Christos Panagiotopoulos, Vladislav Mantic
The quasistatic rate-independent evolution of a delamination at small strains in the so-called mixed mode, i.e.~distinguishing opening (Mode I) from shearing (Mode II) is rigorousl…
A simple and efficient BEM implementation of quasistatic linear visco-elasticity
C. G. Panagiotopoulos, V. Mantic, T. Roubicek
A simple, yet efficient procedure to solve quasistatic problems of special linear visco-elastic solids at small strains with equal rheological response in all tensorial components,…
Quasistatic adhesive contact delaminating in mixed mode and its numerical treatment
Martin Kruzik, Christos G. Panagiotopoulos, Tomas Roubicek
An adhesive unilateral contact between visco-elastic bodies at small strains and in a Kelvin-Voigt rheology is scrutinized, neglecting inertia. The flow-rule for debonding the adhe…
