Contributions to the anisotropic elasto-plastic analysis of shells
… shells. This work contributes to the anisotropic elasto-plastic analysis of shells by addressing key issues in developing shell elements for finite element analysis and an elasto-plasticity model considering anisotropy and its evolution. First we develop a shell element that models the …

Time intergration schemes for rate dependent elasto-plastic constitutive equations
… within the context of a rate dependent plastic material obeying the Von Mises yield condition. Material update procedures which have been used and analysed frequently are the Generalised Midpoint Algorithm, including the Midpoint Method, the Trapezoidal Rule and the Backward Euler Method …

Elasto-plastic stress analysis of curved structures with rectangular section
… important. By applying the methods of plastic analysis, the collapse load of a structure can be determined, and also the stress distribution and the deflection, just before collapse, can be calculated. However the evolution of the stress distribution and the deflection at any section of …

Analysis of the pressuremeter test by FEM formulation of the elasto-plastic consolidation
A decade has passed since the development of the self-boring pressuremeter (SBPM). Even though the device has been recognized by the geotechnical engineering profession as having high promise for evaluating in-situ stress-strain behavior of soils, its use is limited. In large part, this is due to …

Matrix-fiber stress transfer in composite materials elasto-plastic model with an interphase layer
… This scheme takes into account the elastic-plastic behavior of both the matrix and the interphase, and it includes the treatment of stress concentration near the discontinuities of the fibers. The radius of the fibers and the mechanical properties of the matrix were varied in order to …

Optimal Blast-Resistant Sandwich Structures with Transversely Isotropic, Elasto-plastic Polymeric Foams as Cores
Polymeric foam cores are widely used as core materials in sandwich panels subject to blast loads, where high strain rates of the order of 4000 /s are observed. Unlike metallic foams polymeric foams exhibit transversely isotropic response when tested in a laboratory setting. More specifically, they …

Three-dimensional transient thermo-elasto-plastic modeling of gas metal arc welding using the finite element method
As an initial step to three-dimensional thermo-elasto-plastic modeling of Gas Metal Arc Welding (GMAW), a three-dimensional finite element transient heat transfer model has been developed for the autogenous Gas Tungsten Arc Welding (GTAW) process which does not require the complicated metal …
