A framework for development of constitutive models based on semi-micromechanical aspects of plasticity is proposed. The resulting of this model for material employed friction type failure criterion, sub-loading surface, and associated flow rule. This model is capable of predicting effects of the rotation of principal stress/strain axes and consequent plastic flow, induced anisotropy of strength...

in this paper, a method to determine the material parameters of the lemaitre damage model from the knowledge of the gurson model parameters is proposed. as for porosity damage, the gurson model neglects the coupling of elasticity with damage, allowing to use the stress softening effect to make a link between both theories up to a fast identification procedure (based on the expressions of the yi...

This study aims to examine the model's self-activity into relationship between costs and income that will be received as a result of demonstration activities. The revenues model has unconsciously consists material non-material, in which itself calculates what must incurred. research method is qualitative uses case approach. results this reveal there accounting form calculating incurred when sig...

A finite element model based on the layerwise theory is developed for the analysis of transverse cracking in cross-ply laminated beams. The numerical model is developed using the layerwise theory of Reddy, and the von Kármán type nonlinear strain field is adopted to accommodate the moderately large rotations of the beam. The finite element beam model is verified by comparing the present numeric...
