Abstract In this paper, a new homogenization model is developed for the determination of macroscopic shakedown limit state for porous media subjected to general cyclic loads. Based on the variational principle over the stabilized cycle, a new macroscopic fatigue criterion is established, beyond which the collapse of material will occur due to fatigue. Unlike the classical Melan’s theory by statical approaches relying on the complex construction of a time-independent residual stress field, the fo...

This paper is devoted to numerical investigations on mechanical behavior of cracked composite functionally graded (FG) plates. We thus develop an efficient adaptive approach in terms of the extended isogeometric analysis (XIGA) enhanced by locally refined non-uniform rational B-spline (LR NURBS) for natural frequency and buckling analysis of cracked FG Mindlin–Reissner plates. In this setting, the crack geometries, which are described by the level sets, are independent of the computational mesh;...

Abstract This work is devoted to numerical investigation for buckling of functionally graded plates (FGPs) with internal holes using an efficient adaptive isogeometric analysis (IGA). The locally refined (LR) B-splines, which possess the local refinement ability, are used as basis functions in IGA. Kinematics of plate structures are derived using the simple quasi-3D hyperbolic shear deformation theory (S-Q3HSDT), which has few unknowns, free from shear locking, and suitable for considering the s...

Abstract A novel and effective computational approach within the context of isogeometric analysis (IGA) is developed for analyzing size-dependent mechanical behaviors of functionally graded (FG) microbeams. To capture the size effects, an extension of quasi-3D theory is established to integrate with the modified couple stress theory. The nonuniform rational B-spline (NURBS) basis functions are employed and can directly meet the first-order derivative demand of the quasi-3D theory, where four var...

Abstract A two-directional functionally graded microbeam model is developed for natural frequency and mechanical bending analysis by using NURBS–based isogeometric analysis combined with a non-classical quasi-3D beam theory (NCQ3BT). Material parameters of microbeam continuously and smoothly change along thickness and axial directions. The small size effects are seized with the modified couple stress theory. In the NCQ3BT, both normal and shear deformations are considered without the need for th...
