Bending behavior of graded corrugated truss core composite sandwich beams
TL;DR: In this article, a new method for forming the graded corrugated truss core sandwich structures based on an auto-cutting and mold-press process was presented, and the bending stiffness, strength and failure mechanism were investigated.

Response of composite sandwich beams with graded lattice core
TL;DR: In this paper, a new idea combining graded material and lattice core for forming the graded lattice-core sandwich structures is introduced, which is based on the stitching and hot-press process.

Mechanical response of carbon/epoxy composite sandwich structures with three-dimensional corrugated cores
TL;DR: In this paper, a 3D corrugated core sandwich structure was designed and fabricated by auto-cutting process and the failure mechanism of the structure was investigated using analytical models to estimate the strength, stiffness and dominant failure modes.

A multi-scale finite element method for failure analysis of three-dimensional braided composite structures
TL;DR: In this article, the elastic behavior and failure strength of three-dimensional braided composites were investigated by using a multi-scale finite element method under the representative unit cell scale and tow architecture scale.

Thermo-mechanical behavior analysis of 3D braided composites by multiscale finite element method
TL;DR: In this paper, a new multiscale method was developed for the thermo-mechanical performance analysis of three-dimensional (3D) braided composites, which is the extended of multiscscale asymptotic expansion homogenization (MAEH) method and multiphase finite element (MPFE) approach.
