Space flight re-entry vehicles need to withstand heavy impact upon landing and it is critical for engineers to understand the effects on the vehicle and the crew to ensure the safety of the mission.  In order to gain this insight, engineers need to be able to model both the space craft structure and the landing medium such as water, sand, clay, etc.

The coupled Eulerian-Lagrangian (CEL) method in Abaqus/Explicit provides the ability for capturing this interaction all within the framework of a single finite element model.  The simulation provides the means to investigate the peak accelerations faced by the crew or the payload during water landing.    

Mercury Marine outboards, engines, and drives are designed to withstand indoor impact testing (called “logstrike”) that simulates a collision with an underwater object. This test is comprised of an outboard or sterndrive device mounted on a mock boat that collides with a simulated log.

Paper transport is one of the areas under media handling methods where papers are transported by rollers through different path ways. The challenge in media handling is to transport the paper smoothly with out jam or in-plane deviation (paper skew). The smooth flow of paper is influenced by grade of paper, complexity of flow path, roller speed, roller pre-loads and significantly the roller material. It is also costly and difficult to develop a physical flow path testing. Hence, there is a high demand for computer simulation to study the paper flow behavior under different path configurations. In this study a typical printer flow path is considered for paper transport simulation and is carried out with different grades of papers.

PRESS RELEASE
FOR IMMEDIATE RELEASE

July 14, 2011 – Irvine, CA – Nanovea today introduced its patent pending breakthrough method of reliably acquiring yield strength through indentation; ultimately replacing the traditional tensile testing machine for yield strength measurement.

Hello,

I am very new to Abaqus so I apologize since I am probably using the incorrect terminology for this and asking a fairly simple question.

I would like to model a laser beam striking a part the part is rotating w.r.t. the beam and I would like to model this. I have already set up Cylindrical coordinate and I just want the beam to sweep the surface following the equation:

Theta = Omega * Time

where:

Theta:= Angular Position

Omega:= Angular Velocity

Time:= Time

If anyone can offer a suggestion as to how to do this I would be very appreciative.

Regards,

Fractography is the study of features examined on fracture surfaces and has historically been investigated via Microscope or SEM. Microscope being used for macro scale analysis and SEM particularly when it is the nano or microstructure that is vital to the analysis. Both ultimately allowing for the identification of the fracture mechanism type. Although effective, the Microscope clearly has its limitations and the SEM in most cases, other than atomic level analysis, is unpractical for fracture surface measurement and lacks broad use.
