Short Course: Engineering of Durable Elastomeric Structures, 26-27 July 2011, Ann Arbor, Michigan

Submitted by wvmars on

Elastomers are outstanding in their ability to repeatedly endure large deformations, and they are often applied where fatigue performance is a critical consideration. Because the macromolecular structure of elastomers gives rise to a number of unique behaviors, appropriately specialized methods are needed to characterize, analyze, and design for durability. This 2-day course provides the know-how for engineering durable elastomeric components and systems. The course is taught at Axel Products, and includes live demos of typical behavior.

Some Analytical Formulas for the Equilibrium States of a Swollen Hydrogel Shell

Submitted by Song Zilong on

Dear Colleagues,

I wish to bring to you my recent work with my supervisor Hui-Hui Dai on "Some  Analytical Formulas for the Equilibrium States of a Swollen Hydrogel Shell". Below is the abstract and attached is the preprint of the article. I will very much appreciate your comments and suggestions.

what is physical reason behind it?

Hey to imechaica, i am doing my M.E Project in composites.i have done finite element analysis of composite plate with different boundary conditions and  different orientation angle with antisymmetric stacking sequence. i absorve  tip center displacement of cantilever plate is increasing with orientation angle increment and for simple supported plate it decreases.

stacking sequence is [0/-θ/θ/-θ/θ/0] 

please help me to understand this.

<strong>i'm modeling a three pavement layer with tandem loading in explicite mode. i dont know why aborted that analysing with this message:</strong>

 "The ratio of deformation speed to wave speed exceeds 1.0000 in at least one element. This usually indicates an error with the model definition. Additional diagnostic information may be found in the message file.
