Saint-Venant's Principle: Experimental and Analytical

Submitted by Jian-zhong Zhao on

Mathematical provability , then classi cation, of Saint-Venant's Principle are discussed. Beginning with the simplest case of Saint-Venant's Principle, four problems of elasticity are discussed mathematically. It is concluded that there exist two categories of elastic problems concerning Saint-Venant's Principle: Experimental Problems, whose Saint-Venant's Principle is established in virtue of supporting experiment, and Analytical Problems, whose Saint-Venant's decay is proved or disproved mathematically, based on fundamental equations of linear elasticity.

Continuous Stribeck Curve Measurement Using Tribometer

Submitted by NANOVEA on

Irvine, Calif., Oct 24, 2013 – Nanovea demonstrates for the first time the ability to measure a continuous Stribeck Curve. Using the Nanovea Tribometer advanced speed control, from 2000 to 0.01 rpm, within 10 minutes software monitoring provides a complete Stribeck Curve. Prior to this advancement a Stribeck Curve has been shown to be evaluated in a stepwise fashion requiring data stitching. This advancement provides precise data throughout lubricant regime evaluation and substantially reduces time and cost.

Electrothermal Analysis followed by a Stress analysis

Submitted by froblespoblete on

Hi,

 I am currently modeling an electrothermal actuator.

I want to see the displacement that a device can generate when I apply a voltage difference between its ends.

 First, I run a coupled thermal-electric simulation and got the temperature profile. Finally, I run a Static, general analysis to get the displacements, using the temperature profile as a Predefined Field.
