The Executive Committee of the ASME Applied Mechanics Division is pleased to announce and congratulate Professor James R. Barber, University of Michigan, as the recipient of the 2015 Ted Belytschko Applied Mechanics Award. This award will be presented at the AMD Honors and Awards Banquet, tentatively scheduled on Tuesday, November 17, 2015, during the ASME International Mechanical Engineering Congress and Exposition, to be held in Houston, Texas, November 13-19, 2015.

How to prevent non-physical interpenetration of particles

Submitted by nizanth on Sat, 01/03/2015 - 08:31

Hi all,

I was trying to simulate the mode 2 delamination using End loaded split test using meshfree method (RKPM) by coding in MATLAB. Traction separation law is implemented.

When upward load(displacement controlled) is applied at the bottom portion of the bottom lamina, the bottom lamina is penetrating into the first lamina. At the surface where contact is happening, there is no traction transfer happening.

In ABAQUS, we can define a contact surface and interpenetration can be prevented, ensuring traction transfer.

Simpleware Webinars: Intro to Animations Tools and New Physics Modules - February 11th and 18th

Submitted by Simpleware on Fri, 01/02/2015 - 16:31

(re-arranged from January 14th and 21st)

We're running two webinars in February on the latest additions to our software ScanIP's 3D image processing, visualisation and model generation capabilities. The webinars are ideal for existing users and those wanting to learn more about creating models from 3D images.

Introduction to the new ScanIP Animations Tool on February 11th (8am/5pm GMT)

A Review of Quantitative Phase-Field Crystal Modeling of Solid–Liquid Structures

phase field crystal

Phase-field crystal (PFC) is a model with atomistic-scale details acting on diffusive time scales. PFC uses the density field as its order parameter, which takes a constant value in the liquid phase and a periodic function in the solid phase. PFC naturally takes into account elasticity, solid–liquid interface free energy, surface anisotropy, and grain boundary free energy by using this single-order parameter in modeling of coexisting solid–liquid structures.

Effects of geometrical and mechanical properties of fiber and matrix on composite fracture toughness

Submitted by Yuli Chen on Fri, 01/02/2015 - 08:19

Composites reinforced by thinner fibers are intensively studied in recent years and expected to have better
mechanical properties. With development of nanotechnology, the diameter of fiber can be as thin as
several nanometers, such as nanofibers and nanotubes. Then, do these thinner fibers definitely result in
composites with better mechanical properties? In this paper, the toughening effect of reinforcing fibers in
composites is investigated based on the three-level failure analysis model. It is found that thinner

Submissions to JAM have almost doubled

Submitted by Yonggang Huang on Wed, 12/31/2014 - 14:21

The submission to JAM in 2013 was ~42 manuscripts/month. Probably because of its rapid review process (1st round of review ~ 10 days, and 2nd round of review ~24 days including authors' revision time) and rapid publication (online within 48 hours after acceptance), the monthly submission is nearly doubled now. For example, the submission in December, 2014 is 78 in a single month.
