## Stribeck Curve Analysis Using Tribometer

When lubrication is applied to reduce the wear/friction of moving surfaces an increasing load can shift the lubrication from several regimes such as Boundary, Mixed and Hydrodynamic Lubrication. The fluid viscosity, the load that is carried by the two surfaces and the speed that the two surfaces move relative to each other combine to determine the thickness of the fluid film. It is this process that determines the lubrication regime. How the regimes react to friction is shown in what is called a Stribeck curve.

## Crash Prediction for Marine Engine Systems Presented at the 2008 Abaqus Users’ Conference

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 Flow Simulation Using Abaqus

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.

## Breakthrough Indentation Yield Strength Test

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.

## Modeling time dependent function in Abaqus/CAE

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

## Nanoindentation Creep Measurement

Creep can be characterized as the result of a solid material that is slowly and permanently deformed under the influence of stress. Deformation results from the consistent stress below the yield strength of the material. The amount of applied stress and its duration can eventually lead to the failure of the given material. Ultimately, it is for this reason that Nanoindentation creep measurement provides crucial information to study material behavior.

## negetive spring

Can some one suggest different ways of making spring of negetive spring constant??

## vibration test fixture design

Hello all,

I am a fresher; I just started working for a company leading in passenger cars.
I have been given a project in which I have to design a vibration test fixture for passenger car bumper.
Currently, we manufacture fixture in-house. And for every bumper, separate fixture is made.
My task is to design a test fixture (for testing frequency range of 0- 70 Hz) which will be modular.

## Paper Roughness Measurement With 3D Profilometry

Paper surface topography is vital to the intended use and quality of the product. To control paper product quality it will heavily rely upon quantifiable, reproducible and reliable surface measurement. Precise surface measurement and evaluation of a paper product can lead to the best selection of processing and control measures. The Nanovea 3D Non-Contact Profilometer utilize chromatic confocal technology with unmatched capability to measure paper surfaces.

Hello everybody,
I am trying to model a plate (shell elements) supported on rubber bearings and columns (beam elements) and I would like to know how to release rotational degrees of freedom at one or both ends of a beam element in Abaqus/Explicit.
Unfortunately, the keyword *RELEASE only works in Abaqus/Standard.
Thanks in advance for your kind help. Regards,

## The Understated Contributor to International Economic Recovery

While R&D topics continue
to lead as a beacon for economic recovery, a crucial part of the R&D process
continues to receive little to no attention. And make no mistake, you are about
to learn of the single most important factor in the advancement of new or
improved material technologies around the world.

## Internship in Computational Mechanics (plasticity)

Dear Members,

Hope you will be fine.

I am student in MSc Computational Mechanics, here in Nantes France. I am looking for an internship  which is compulsory part of master degree. I am interested in materials, processing/modeling and simulation. I would be grateful for your guidance and help.

Thanks and Regards,

## Soil Pile imteraction in ANSYS ASAS-NL

Hi,

In order to model a jacket supported by four piles I need to model the interaction between soil and piles in ANSYS ASAS-NL. As I want to make a trasient analysis I use ASAS-NL which unfortunately do not interact with SPLINTER. The jacket structure is modelled by 3D beam elements. Can someone tell me how I model the soil pile interaction? Is it possible to make use of P-Y and T-Z curves in ASAS-NL?

## ANSYS CODE FOR FATIGUE CRACK PROPAGATION

Hi all,

Currently, I am using ANSYS 12.1 for the fatigue crack propagation simulation for the edge crack & center crack plates. It is a mixed mode crack propagation.

Can anybody please tell me or guide me how to write the code in the ANSYS using APDL for automatic remeshing around the cracktip when crack propagates to the new position?

Thanks in advance. :)
