Abstract: This paper presents a parametric study of the effect of delamination, and of initial imperfection, on the overall nonlinear behavior of laminated composite beams. The study is based on geometrical ...

Abstract: A geometrical nonlinear theory of composite laminated beams is derived with the effect of transverse shear deformation taken into account. The theory is based on a high-order kinematic model, ...

Abstract: A three dimensional incompressible and geometrically as well as materially nonlinear finite element is formulated for future implementation in models of cardiac mechanics. The stress-strain relations ...

Abstract: An analytical model of the post-buckling behavior of a beam under contact constraints was derived. Experiments were carried out in order to characterize the various phenomenon involved in the ...

Abstract: The thermoelastoviscoplastic buckling behavior of cylindrical shells under axial compression is investigated. The analysis is based on nonlinear kinematic relations and nonlinear rate-dependent unified constitutive equations. ...

Abstract: A two-dimensional incompressible plane-stress finite element is formulated for the simulation of the passive-state mechanics of thin myocardial strips. The formulation employs a total Lagrangian ...

Abstract: The bending behavior of an unsymmetrical sandwich beam with a flexible, foam‐type core is investigated analytically. The beam consists of different skins, upper and lower, metallic or composite‐laminated, and a soft core. ...

Abstract: A general, high‐order theory based on variational principles is presented for the bending behavior of a sandwich beam with a core that is vertically flexible. The theory embodies a rigorous and systematic approach to the ...

Abstract: A three-dimensional constitutive law is proposed for the myocardium. Its formulation is based on a structural approach in which the total strain energy of the tissue is the sum of the strain ...
