A crystal plasticity continuum theory with length scale dependent internal residual stress and free surface effect

Submitted by RaminBabaei on

The long range elastic interaction between dislocations is naturally accounted in
discrete dislocation plasticity through stress field of individual dislocation.
In addition, the dislocation boundaries elastic interaction is considered via
image stress superposition approach in the finite element framework. In current
study these interaction terms are considered in crystal plasticity framework
through length scale dependent internal residual stresses which are arise from

Frequency analysis with Contact constraint

Submitted by sidd04mech on

Hi,

 

I am trying to analysis a model in ABAQUS with a plate bolted to the Bracket top surface at 4 ends. I have to define contact between them (and also bolted at 4 ends) to get the Modal frequency. But When I searched for it, I got the answer that contact doesn't work with Modal analysis as contact is a nonliner problem and Modal Analysis only solves linear problem.

 

Initiating in hybrid composite research?

Submitted by karan dhanjal on

hello everyone..i am a beginner in this field so ultimately seek help in order to escalate in my research.Currently i am working on hybrid composites using graphite filled FRPCs so kindly encourage me and help me make up my mind for better understanding in order to have an effective research.I am concentrating on tribological properties and if there is anything i can possibly implement to make it more profound please guide me so.I am working on my theoratical thesis right now.

Simple metal cutting example with chip formation in ABAQUS

Submitted by Borad M Barkachary on

Hello every one....



I am new in abaqus/cae, abaqus/explicit.  I have googled but not able to get any tutorial or example for metal cutting with chip formation. just few youtube animation videos are available on 3D orthogonal cutting, milling. But now such video or doc is available.



So, if any one having any kind of tutorial, example, or short notes.. please please share with me or mail me on my ID badwl24 [at] yahoo.com.
