Can you become a mechanic by reading books?
Well I am really wondering about thsi right now as I read that I should really try to further my education via Distance learning .
Cyclic volume changes in rubber
This is a study dealing with the volume variation in filled crystallizable natural (F-NR) and uncrystallizable styrene butadiene (F-SBR) rubbers subjected to cyclic loadings. During their deformation, such materials exhibit volume variation induced by the cavitation phenomenon and the decohesion between particles and the rubber matrix.
Volume variation in filled and unfilled natural rubber : competition between cavitation and stress-induced crystallization
this is a study on the competition between cavitation and stress-induced crystallization during the deformation of cis-1,4 polyisoprene rubber. During deformation, this kind of material exhibits volume variation induced by both phenomena. In this study, we propose to measure this volume variation by an original full-field measurement technique. The high resolution of this technique allows us to identify characteristic stretch ratios during mechanical cycles.
advice to understand the Gurson Model
Forums
Recently, I am studying on the Gurson Model, but it is a little bit hard for me to understand most part in the paper 'Continuum Theory of Ductile Rupture by Void Nucleation and Growth', I don't know about the spirit of deduction of formulas and some keywords make me confused, like 'convexity'and 'normality','loci',many....
It may be helpful if someone who is highly understand better about Gurson can introduce me some references maybe basic or middle hard, Thanks!

Is it possible to find out the number of cycles to failure for a composite material(glass-epoxy) in ansys,with the data known only for material properties,layup,fibre orientaion?The beam (i.e.solid 191 taken for analysis of composite) is to be considered to be given a displacment at one end.

Multiscale Science Based-Modeling and Simulation and Experimental Validation on Enabling Materials, - Deadline March 1
On behalf of the NSF Summer Institute on Nanomechanics, Nanomaterials, andMicro/Nanomanufacturing, I am writing to remind you that the deadline for application for fellowships is March 1, 2009, for the short course entitled "Multiscale Science Based-Modeling and Simulation and Experimental Validation on Enabling Materials", to be offered from May 27 to May 30, 2009 in Evanston, Illinois. The short course will first cover science-based modeling and simulation methods for general classes of enabling materials.
Hard stage materials in Ansys
Hello,
I'm trying to simulate and compare principal stresses in model of bolt and nut, for different material data. I would like to get the soft/hard stage comparison. The problem is that I just do not know how to define hard stage material, it is not in standard material library in ansys (workbench or classic).
If anyone could help me giving some examples of hard stage materials data I would be greatfull.
