Résumé

On the basis of linearized equations of the theory of curvilinear bars, the buckling problem of rectilinear short and long laminated fiber reinforced specimens under the three-point bending conditions has been formulated. Using the method of finite sums in the variant of integrating matrices, a numerical method for solving the above problem has been developed. It has been shown that the failure of the composite specimens under the three-point bending conditions occurs due to the implementation of non-classical shear buckling mode.

Détail

Keywords: layered composite, specimen, three-point bending problem, finite sum method, mechanical test simulation, shear buckling mode.
