For a particular tool, the edges precision is expected to meet intended results during use in machining. Because the depth of cut is controlled to the nanometer level, the tool cutting edge profile is an important factor to influence the final quality of a machined surface. By analysis of a 3D-Profilometer the edge correctness can be determined to insure quality control before production and or during the life of the tool.

Dear All,

cohesive zone modeling of interface fracture : comparisons

Submitted by Laurent Champaney on Fri, 01/22/2010 - 18:53

Hello,

(for completing R. Huang's post : node/7396).

A few years ago, some colleages (from Italy, UK and Brazil) and I proposed some comparisons of the behavior of cohesize zone models. This was presented during ECCM 2004. The paper is attached.

Simulate moving laser beam on a plate in ANSYS

Submitted by daltoy3 on Fri, 01/22/2010 - 04:26

Hi everyone!

I've been trying ansys for a few weeks but in vain. I'm trying to inject a heat source(laser) on a 2D rect plate. I'm not sure on the corrct way to add the boundary conditions. This is what I do:

1. assuming room temp so i added 298K to the bottom, left and right using define loads >add_temp>lines

2.next i inject a heat source say 1000K using define loads>add_temp_on nodes to a few surface center nodes (meaning the top surface still have undefine boundary conditions)

How to classify vehicle parts into sprung and unsprung mass?

Submitted by vinay.warrier on Thu, 01/21/2010 - 05:36

I am currently working on deriving equations for different vehicle models using Lagrangian and Newtonian methods. I am need of parameters to test few MATLAB models, and in vague to know exactly how to classify the mass into sprung and unsprung. Similarly, how do I obtain the MOI separately for the unsprung mass?

Connector - Join + Cardan

cardan

join

hi, i am using connector - jin + cardan to connect 2 beam elements; a beam and a column.

i applied a tip load to the edge of the beam in abaqus standard. for the connector, i keyed in the elastic properties and the plastic properties in terms of plastic moment and plastic rotation.

Shape alloy

thank you for comments. Could you clarify to me what do you mean from generation force? as I know there is no generation force. in fact i think this is a energy transformation.
