In this paper, progressive damage and global failure of composite laminates under quasi-static, monotonic loading are investigated using 3D continuum damage mechanics. For this purpose, a finite element program has been developed using an eight-node 2D layered element including layer-wise plate theory. Damage analysis of a single orthotropic layer under various uniform in-plane and transverse l...

In this study, based on nonlocal differential constitutive relations of Eringen, the first order shear deformation theory of plates (FSDT) is reformulated for vibration of nano-plates considering the initial geometric imperfection. The dynamic analog of the von Kármán nonlinear strain-displacement relations is used to derive equations of motion for the nano-plate. When dealing with nonlineariti...

Over the past few decades, prospect of energy generation from an oscillating piezoelectric patch has gained attention. A typical setup this kind would be a mounted on flexible plate that is exhibiting self-sustained flapping motion. Piezoelectric patches are generally multilayered consisting piezoelectric, substrate and electrode layers placed top each other. In paper, we first propose quasi-mo...

Cobalt-doping a NiTi layered double hydroxide affords CoNiTi-LDH with smaller plate sizes and higher degree of order, which allows the band gap to shrink from 2.7 eV 2.4 eV. is active for both water oxidation reduction.
