摘要:Abstract(#br)A strain-based continuum damage-elastoplasticity formulation at finite strains is proposed based on an additive split of the stress tensor. Within the proposed framework, a hyperelastic extension of the classical J 2 -flow theory is developed as a model problem, with...

摘要:Abstract(#br)Ket qualitative features of solutions exhibiting strong discontinuities in rate-independent inelastic solids are identified and exploited in the design of a new class of finite element approximations. The analysis shows that the softening law must be re-interpreted i...

摘要:Abstract(#br)A recently proposed methodology for computational plasticity at finite strains is re-examined within the context of geomechanical applications and cast in the general format of multi-surface plasticity. This approach provides an extension to finite strains of any inf...

摘要:Abstract(#br)In the absence of external loads or in the presence of symmetries (i.e., translational and rotational invariance) the nonlinear dynamics of continuum systems preserves the total linear and the total angular momentum. Furthermore, under assumption met by all classical...

摘要:Abstract(#br)An algorithm designed for the determination of equilibrium shocks that appear in quasi-static evolution problems associated to elastic nonmonotonous stress-strain laws is presented in the context of one-dimensional media. Two basic procedures are involved in the prop...

摘要:Abstract(#br)A single asymptotic derivation of three classical nonlinear plate theories is presented in a setting which preserves the frame-invariance properties of three-dimensional finite elasticity. By a successive scaling of the external loading on the three-dimensional ...

摘要:Abstract(#br)A path domain independent integral, S, that equals the energy release rate for an extending crack in a thermoinelastic field is presented. This paper develops the new parameter from its theoretical foundations in continuum mechanics, demonstrates that S can be calcul...

摘要:Summary(#br)Three conservation laws are associated with the dynamics of Hamiltonian systems with symmetry: The total energy, the momentum map associated with the symmetry group, and the symplectic structure are invariant under the flow. Discrete time approximations of Hamiltonian...
