A New Element Model of Solid Bodies

Submitted by Jiang Ke on Sat, 10/26/2013 - 13:27

Based on the generalized Hooke's law and the superposition principle, a new element model of linearly elastic and orthotropic solid bodies is presented. Furthermore, the paper provides a new method for analyzing solid bodies. This new element is a simple truss, and a solid body is considered to consist of many such truss elements, then the solid body becomes a truss structure. Thus the internal forces and displacements of the solid body can be obtained by calculating this truss structure.

Saint-Venant's Principle: Experimental and Analytical

Submitted by Jian-zhong Zhao on Sat, 10/26/2013 - 02:09

research

Mathematical provability , then classication, 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.

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.

Hi,

I started a research project on Impact problem of nonlinear beam (all kind of nonlinearity). Has anyone studied on this issue? Please give me some reference or direction. It will be a great help. Thank a lot

Best regards.

Electrothermal Analysis followed by a Stress analysis

Submitted by froblespoblete on Thu, 10/24/2013 - 13:20

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.
