Computer Simulation of Nonisothermal Elastoplastic Shell Responses

摘要: Shell structures are extremly efficient, thin walled load-carrying components, in the elastic as well inelastic regime. Realistic and efficient computational strategies lately rapid development. Such strategy for modelling of nonisothermal, highly nonlinear hardening responses elastoplastic shell analysis has been proposed this article. Therein, closest point projection algorithm employing Reissner-Mindlin type kinematic model, completely formulated tensor notation, is applied. A consistent tangent modulus ensures high convergence rates global iteration approach. The integration implemented into a layered assumed strain isoparametric finite element, which capable geometrical nonlinearities including rotations. Under assumption an adiabatic process, increase temperature analysed during deformation. Finally, numerical examples illustrate robustness efficiency algorithms.
