Delamination influence on elastic properties of laminated composites

Finite Element Modeling of Delamination Crack Propagation in Laminated Composites

Finite element analysis of the delamination crack propagation in laminated composites is presented. Fracture mechanics based Virtual Crack Closure Technique (VCCT), and the cohesive element technique, have been used to simulate the delamination initiation and propagation under Mode-I type loading. Detailed description of the parameter selection process for these two techniques with ABAQUS®/Stan...

Influence of Fiber Orientation and Thickness on Tensile Properties of Laminated Polymer Composites

The objective of this research was to gain a better understanding of tensile properties of epoxy resin composites reinforced with glass fiber. The effect of fiber orientation & thickness of laminates has been investigated & experimentation was performed to determine property data for material specifications, the laminates were obtained by hand layup process. The laminates were cut to obtain AST...

A Numerical and Experimental Investigation on Delamination Buckling Behavior in Laminated Composites under Compressive Load

On the influence of delamination on laminated paperboard creasing and folding.

Laminated paperboard is used as a packaging material for a wide range of products. During production of the packaging, the fold lines are first defined in a so-called creasing (or scoring) operation in order to obtain uncracked folds. During creasing as well as folding, cracking of the board is to be avoided. A mechanical model for a single fold line has been proposed in a previous study (Beex ...

Mechanical Properties of Angle Ply Laminated Composites- A Review

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 ...
