Trying to model a crossply square plate with a sinusoidal temperature loading (uniform along the thickness). I am trying to match the results by Kant et al 2008 and Rohwer et al 2001. I am modeling the compoosite as a 3-D solid elements (making a part and dividing into 4 layers). I always obtain transverse shear stress on the 90 degree layer at 0,b/2,z to be zero.  My results match with that of the paper when I have a single layer of orthotropic material but they dont match when I have 4 layers of equal thickness and an aspect ratio of 5 (length/thickness).

Hello everyone,

I'm a beginner in Abaqus. I must simulate effect of water stream on thin membrane contactin with ground. Which element type do you suggest? Can STRI65 be a good option?

Thanks in advance

Petroleum Field Services team is currently looking for Coil Tubing Field Engineers. coiled tubing refers to a very long metal pipe, normally 1" to 3.25" in diameter. which is supplied spooled on a large reel. Petroleum engineering is primarily concerned with the economic extraction of oil, gas and other natural resources from the earth. It is involved in nearly all of the stages of oil and gas field evaluation. There are divided into several group such as petroleum geologists, reservoir engineers, production engineers and drilling engineers.

 A 1-year post-doctoral position is available at École Polytechnique to work on the experimental characterization and the multiphysics modeling of carbon nanotube based sensors.

The viewpoint that cavitation in rubber — that is, the sudden growth of inherent defects in rubber into large enclosed cavities in response to external stimuli — is a purely elastic phenomenon has long been known to be fundamentally incomplete. Essentially, this is because the local stretches around the defects at which cavitation initiates far exceed the elastic limit of the rubber, which therefore ought to inelastically deform by fracturing to accommodate their growth.

Dear Colleague,

I would like to inform you that the annual report on the scientific and educational activities carried out by the research unit MUSAM on Multi-scale Analysis of Materials at IMT Lucca during 2014 can be downloaded from the following link:

Webinar 1 - Design of high efficiency Turbocharger/e-charger compressors by 3D Inverse design method

In this one hour free webinar we will use two specific examples to show how and why the 3D inverse design method can result in breakthrough designs that improve the turbocharger efficiency and yet meet the requirements for good stress and vibration and wide operating range. The two cases will be:
