Torsional effects in structures subjected to strong ground motion
… ground motion were investigated; both linear and nonlinear material behavior were considered. Emphasis was placed on the strong torsional coupling associated with the beating phenomenon in the seismic response of structures with small static eccentricity and closely spaced frequencies. In order to …

Hierarchical material models with microstructure for nonlinear analysis of progressive damage in laminated composite structures
This study presents new comprehensive nonlinear structural modeling approaches using hierarchical 3D micromechanical models for the analysis of progressive damage in laminated structures. Each approach is generally a synthesis of three components: a nonlinear material model for the matrix behavior; …

Geometric and material nonlinear effects in elastic-plastic and failure analyses of anisotropic laminated structures
… element that includes linear elastic and plastic material behavior with full geometric nonlinearity is used to determine stresses at selected points (Gauss quadrature points in each element) of the structure. Material stiffness (constitutive) matrices are evaluated at each Gauss point, in each …

Vliv geometrie vzorku na úroveň zavíracího napětí před čelem únavové trhliny
… a zavíracích napětí na konečnoprvkových modelech dvou odlišných únavových vzorků, a to vzorků „compact tension specimen“ a „center cracked plate tension specimen“, s použitím nelineárního materiálového modelu. Modelování celého jevu je prováděno pomocí metody konečných prvků v …
