Numerical simulations are performed of the turbulent flow and thermal field in a structured porous media. The geometry of interest is an open lattice structure that is made up of mutually orthogonal, millimeter-scale, thermally conductive cylindrical elements. A large-eddy simulation (LES) is performed and the results are used as reference data to evaluate the performance of three commonly used...

The purpose of this study is to review many of the available guidelines for Polymer composite materials. Guide lines for failure mode, laminates orientation, winding angle, water absorption, as they strongly influence the mechanical properties of composite materials. The present review is focused on composite laminates made of glass, carbon, graphite, hybrid and natural fiber composites, since ...

Fiber Metal Laminates (FMLs) are hybrid materials that combine metal components with fiber-reinforced composites. The properties and failure modes of CArbon fiber Reinforced composites/Aluminum (CARALLs) composed T700/PA6 unidirectional prepreg 6061 aluminum alloy were studied using experimental numerical simulation analysis. Through three-point bending experiments, the behavior CARALLs differe...

In this paper, an algorithm for the coupled simulation of circuit and piezoelectric laminate devices is presented. A finite element solver for piezoelectric laminates is included in the SPICE framework as a capacitor. The charge of this capacitor is a function of both the terminal voltage and the mechanical strain in the piezoelectric material. The coupled simulator allows simulation of novel m...

Fibre metal laminates (FML) are hybrid materials perspective for wind-turbine, containers and marine objects, besides the aerospace industry. During manufacturing process some faults can occur be hazardous reliability of FML structures. One most critical defects kissing bonding due to their lack detectability strength compared traditional delamination defect. The quantitative explanation were u...
