impact damage due to laminar construction??

Submitted by setareh on

Hi everyone,

 

According to a book chapter written by NL Hancox, 'Laminar construction of composites which is required if the reinforcing fibres are to be used efficiently and anisotropy reduced, can be a reason why composite laminates are vulnerable to impact damage.'

Now I have three questions;

1-What is meant here by the specified 'laminar construction to reduce anisotropy'?Does it mean to use different orientation for fibres in each ply to have an isotropic material at the laminate level?

2011 International Dictyostelium Conference, August 14-18, Baltimore, MD USA

Submitted by Tian Zhi Luo on

The annual International Dictyostelium Conference will be held in Baltimore, MD USA from August 14 to 18. Dictyostelium has been extensively used as a model organism for the study of cell mechanics, motility, chemotaxis, cell division and other biological events that involve cell shape change and the mechanical behaviors of cells. In this coming meeting, there will be 70 oral presentations and 100 posters covering above topics.

Using Abaqus/Explicit to model polymeric thin-film mechanical property changes due to embossing

Submitted by SIMULIA on

Embossing of polymeric films destined for usage in the personal care marketplace is an industrial process that produces a very fine pattern, barely discernible to the naked eye, yet has a significant influence on some market-driven properties; more bulk, a soft and smooth touch, reduced crinkling noise and lower gloss. However this comes at a cost to the mechanical properties such as stiffness and ultimate strength capability.

Study of a Diaper on a Moving Baby using ABAQUS

Submitted by SIMULIA on

ABAQUS is used to simulate interactions of an absorbent personal care product (a diaper), with its user and their environment. This problem, being almost completely driven by complex contact between highly deformable and moving bodies, is a challenging proposition. Advanced contact algorithms, non-linear material models and multi-body dynamic analysis capabilities in ABAQUS are used to successfully study the structural interactions of a diaper, a baby and their environment.
