Three-dimensional stress analysis for laminated composite and sandwich structures

experimental bending analysis of strip sandwich and laminated composite plates

there exist simple theories to predict the strain of sandwich structures under a bending load and specific support conditions. although theoretical predictions are highly effective, but the role of testing in validation of these theories and their progress is undeniable. the main goal of the present paper is to prepare a test instruction in order to minimize the error of data acquisition and th...

Three Dimensional Analysis of Laminated Cylindrical Panels with Piezoelectric Layers

A semi-analytical solution is presented for three dimensional elastic analysis of finitelylong, simply supported, orthotropic, laminated cylindrical panels with piezoelectric layers subjected to outer pressure and electrostatic excitation. Both the direct and inverse piezoelectric effects are investigated. The solution is obtained through reducing the highly coupled partial differential equatio...

Analysis and Optimization of Laminated Composite Shell Structures

The objective of the present work is to develop finite element based optimization techniques for laminated composite shell structures. The platform of implementation is the finite element based analysis and design tool MUST (MUltidisciplinary Synthesis Tool) and a number of features have been added and updated. This includes an updated implementation of finite elements for shell analysis, tools...

Dynamic Analysis of Three Dimensional Asymmetric Isolated Structures

Multiscale Approach to Damage Analysis of Laminated Composite Structures

The presented work depicts results of a two-scale approach to the problem of damage and failure prediction on laminated composite structures. Modeling on the micro-level has enabled insight into the underlying physical processes which lead to homogenized properties of the macro-scale material. In this work, micromechanical analysis has been performed by application of the High Fidelity Generali...
