Hello Users,
I have a report which validates particular material model available in FEA by doing FEA tensile test against experimental tensile test data of the material.
FEA tensile test process:
Create specimen model - mesh - apply load - calculate displacement - calculate strain and...
Hello users,
Befor posting here, i have gone through previous posts regarding my doubt. Still, i am not clear.
so my queries are interpretations of principal stresses.
1. Principal stresses are scalar or vector? If it is vector, then does it depend on the way of mesh is generated.
2. In...
Hello users,
Is it possible to import Abaqus/cae file into Hypermesh. (Like Viceversa is possible with *.inp file format from Hypermesh).
Thanks for any help.
Hello Users,
I am trying to apply a acceleration load to a one side fixed cantilever beam(shell element) to do frequency response analysis.
I tried 2 options.
1. I used DAREA in constraint and in Z direction constraint i used 5(Acclen Value). In Dload Panel, i changed it to Acceleration...
Hello Forum users,
we have a problem of warpage with one big plastic (PP 30% glass filled) component like all plastic products. we did the moldflow analysis and got warpage results. Cooling is also considered during the analysis.
Warpage says 0 to 24 mm. But Moldflow engineer says(other...
Hello Forum Users,
How to interpret the von mises stress and displacement results from normal mode analysis.
I assume,
Normal mode analysis does not give exact displacement value. (Frequency response analysis is required). So, stress output is also not correct.
2. Model: 100*10*1.5 mm...
Hello users,
How to get stress values at particular strain or displacement like 5%, 10%, 15% and so on.
In my compression analysis, i get results randomly.
I use abaqus CAE.
Thanks for your time and help.

Hello users,
From Nominal stress-strain curve(compressive), I calculated logarithmic plastic strain using following formula.
Log plastic stain = Nominal strain - (true comp stress/E)
Is it right? I get ascending values till 75% strain then my log plastic strain descends. Abaqus asks for a...
Hello,
I need to apply moment load on my whole body (1200 Nm) about some reference point.
first option, make analytical rigid body and linked with reference point. It leads to contact analysis and makes it difficult. Does not converge.
second option, kinematic coupling. But it removes...
Hello,
I am creating midplace surface model from my solid part for analysis purpose. when i try to join two surfaces i get non connex error. For example, flat surface (100*100 mm) is connected with another flat surface (50*50 mm) which is perpenticular to first surface.
I get this error at...
Hello,
I have part with 600*300*10 mm. I need atleast 3 layers of elements thru 10mm thickness and same time less no of elements on other surfaces. Global meshing produces very fine mesh on every area.
What should be my approach? I am new to femap.
Thanks,
feaplastic.
Hello,
I ran a geometric nonlinear analysis, my results are quiet ok. But i want to ensure analysis has been done in a right way. For example in another thread, I read something like strain energy density must be converged for a correct analysis. But now, I could not find that thread abt...
Hello,
I would like to see my displacement results with respect to user defined coordinate system(which i defined to specify boundary conditions) rather than global coordinate system.
How to do in abaqus.
Thank you,
