摘要:Abstract(#br)A surrogate modelling strategy for predictions of interval settlement fields in real time during machine driven construction of tunnels, accounting for uncertain geotechnical parameters in terms of intervals, is presented in the paper. Artificial Neural Network and P...

摘要:Abstract(#br)The role of the stress measure to be chosen as the argument in the definition of yield functions is discussed in the context of finite strain plasticity theory. Motivated by physical arguments, the exponential algorithm for multiplicative finite strain plasticit...

摘要:Abstract(#br)This paper presents a higher order spatial discretization concept for multiphase durability-oriented structural analysis. The proposed concept uses hierarchically organized L egendre -polynomials allowing to choose the polynomial order of the field variables fieldwis...

摘要:Abstract(#br)This paper is concerned with a regularization method to avoid slip oscillations of contact nodes resulting from lack of C 1 -continuity of low-order finite element discretizations. The purpose of this method is to enhance the robustness of contact algorithms for 2D c...

摘要:Abstract(#br)This paper addresses the algorithmic consequences of different definitions of the tangential slip in the context of finite element analyses of frictional contact involving large deformations. The algorithmic formulation including consistent contact matrices obtained ...

摘要:Abstract(#br)This paper is concerned with an analysis of the mesh dependence of results from numerical failure analyses using the strong discontinuity approach (SDA) based on an analytical and numerical comparison with a standard plasticity model, pertaining to the classical frac...

摘要:Abstract(#br)The well-known finite element representation of reinforcing bars by means of overlay (“rebar”) elements is recast in the context of finite strain analyses of cord-reinforced composite materials. The variational formulation including the linearized forms is prese...

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...
