cohesive zone modeling of interface fracture : comparisons
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
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?
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?
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.
WARNING: THE AVERAGE FORCE USED TO ENFORCE CONTACT CONSTRAINTS AT NODE SPRING-1.86 IS 383.736E+03 TIMES LARGER THAN
I am trying to simulate and spring analysis by using concentrated force on Abaqus 6.9.
Job cannot be performed due to the following warning and error. May i know the solution!
8th International Tutorial Workshop on PFM and Nanoscale Electromechanics of Polar Materials, August 25-27, 2010, Beijing, China
This workshop aims
to provide in-depth description and recent advances in piezoresponse force microscopy (PFM) and nanoscale
electromechanics. It will introduce basic principles of PFM operation, relevant
instrumental aspects, and image interpretation. The theory of cantilever
dynamics, PFM contact mechanics, resolution theory, and their implications for
qualitative and quantitative data interpretation will be presented. The recent
technical advances, including vector PFM, high-frequency PFM, band-excitation
and DRFT imaging, switching spectroscopy PFM, and imaging and polarization
switching in liquids and vacuum, will also be illustrated. For ferroelectric
and multiferroic materials, applications of PFM for domain imaging, nucleation
