A framework for damage modeling in multi-constituent laminated materials
… and a Discontinuous Galerkin method with return mapping algorithms to allow for damage when undergoing large deformation to be analyzed along the interface of heterogeneous materials. These two methods are collectively used to find weaknesses and faults in newly discovered fibrous and …

Reliability analyses of the collapse and burst of elastic/plastic tubes
… shell theory. This element implements the return mapping algorithm for an elastic/plastic material and includes the effects of shell thinning and geometric imperfections. Incorporation of this finite element program into a reliability program developed for this study provides an effective …

Theoretical and numerical aspects of problems in finite-strain plasticity
… is a viable alternative to the conventional return mapping algorithms. While this alternative approach is not necessarily better than the conventional one for simple models of plasticity, it may prove valuable when considering more complex models for materials which exhibit dissipative …

Towards a material damage model using the logarithmic strain, with von Mises plasticity considerations
… and strain, are computed with the use of the return-mapping method. The stress measures utilised are the 2nd Piola-Kirchhoff stress S and the Mandel stress Σ. The Newton-Raphson update scheme is applied in the plasticity evolution equations via the plastic multiplier (denoted λ), which …
