Journal ArticleDOI
Exact analytical solutions for the local and global buckling of sandwich beam-columns under various loadings
TL;DR: In this paper, the critical values and the associated bifurcation modes of a sandwich beam-column are derived for various loading conditions. And the proposed analytical formulae are validated using 2D linearized buckling finite element computations, and parametric analyses are performed.
Journal ArticleDOI
Exact buckling solution for two-layer Timoshenko beams with interlayer slip
TL;DR: In this article, the buckling behavior of two-layer shear-deformable beams with partial interaction is investigated. But the buckle behavior of the composite beam is not considered.
Journal ArticleDOI
Analytical approach for free vibration analysis of two-layer Timoshenko beams with interlayer slip
TL;DR: In this paper, an analytical procedure for free vibrations of shear-deformable two-layer beams with interlayer slip is developed, where the effect of transverse shear flexibility of two layers is taken into account in a general way by assuming that each layer behaves as a Timoshenko beam element.
Journal ArticleDOI
Homogenization of the elastic behavior of a layer-to-layer angle-interlock composite
TL;DR: In this article, a specific Python program using Abaqus software package is developed, allowing for parameterized geometrical modeling and mechanical analysis in a systematic and efficient way, which enables to consider the real composite architecture after infusion and the yarn damage during weaving.
Journal ArticleDOI
Some new analytical results for plastic buckling and initial post-buckling of plates and cylinders under uniform compression
Philippe Le Grognec,Anh Le van +1 more
TL;DR: In this paper, the theoretical aspects of the elastoplastic buckling and initial postbuckling of plates and cylinders under uniform compression were studied, based on the 3D plastic bifurcation theory assuming the J 2 flow theory of plasticity with the von Mises yield criterion and a linear isotropic hardening.
