contact issues on abaqus

Submitted by Zaki on
Hello
I am trying to model a 2D cylinder Pad on flat Specimen for fretting but I am having some trouble with my results. First I just tried to have the good Hertz's solutions for the contact. So to do that, I chose the pad and the specimen to be deformable but the pad seems to be undeformable in my results (that's weird), 1ST PROBLEM. And the second one is, whatever the amount of force I applied, I have always the same values in my results. I am looking for some help.
I put some pictures to show how I did my modeling and I don't have any convergence errors

A residual stiffness-based model for the fatigue damage of biological soft tissues

Submitted by Hai Dong on

Biologically-derived and chemically-treated collagenous tissues such as glutaraldehyde-treated bovine pericardium (GLBP) are widely used in many medical applications. The long-term cyclic loading-induced tissue fatigue damage has been identified as one of the primary factors limiting the durability of such medical devices and an in-depth understanding of the fatigue behaviors of biological tissues is critical to increase device durability.

Models for peristaltic locomotion in soft robots and worms

Dear Colleague,

I'm pleased to announce the latest paper from my research group (coauthored with Evan Hemingway (PhD 2020)): 

Continuous models for peristaltic locomotion with application to worms and soft robots

has just been published in Biomechanics and Modeling in Mechanobiology. Here's a simulation of the model:

Call for abstracts: Topic on 3D Printed Soft Materials in ASME IMECE 2020

Submitted by Kai Yu on

Dear colleagues: 

We would like to invite you to submit an abstract to the Topic 12-3: 3D Printed Soft Materials at the 2020 ASME  IMECE to be held from November 15 – 19 at Portland, Oregon.

Additive manufacturing, also known as 3D printing, offers unique opportunities to explore novel properties and mechanics of soft materials. This topic calls papers from research efforts related to soft materials with novel properties realized or created using 3D printing techniques. Specific areas of interest include, but are not limited to: 

ICME Prize Competition Open for Submission

Submitted by Wenbin Yu on

 The AIAA with the support of Composite Design and Manufacturing HUB (cdmHUB), NASA (National Aeronautics and Space Administration), and Rolls Royce Corporation funding have established an ICME (Integrated Computational Materials Engineering) prize for the best aerospace-focused ICME project. This bi-annual award will not only include recognition at SciTech 2022 conference, but will also provide a $1,500.00 team award.
