RISA Modified Storen-Rice Bifurcation Analysis of Sheet Metal Forming Limit Diagrams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bifurcation analysis is a theoretical prediction approach to measure the FLD when the localized neck causes development of vertex on subsequent yield surface as was adopted by Storen-Rice. Some ...
An Investigation Into the Prediction of Forming Limit Diagrams for Normal Anisotropic Material Based on Bifurcation Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, formula derivation for bifurcation analysis based on a constitutive model including Hill 48 yield criterion with normal anisotropy of a pointed vertex on subsequent yield loci ...
Investigation of Nonlinear Bending Analysis of Moderately Thick Functionally Graded Material Sector Plates Subjected to Thermomechanical Loads by the GDQ Method
Publisher: American Society of Civil Engineers
Abstract: Large deflection analysis of functionally graded annular sector plates subjected to thermomechanical loads is presented. Based on the first-order shear deformation theory in conjunction with nonlinear von Kármán assumptions, ...
