Dear all,
Sometimes, we can see the conception of Mandel Stress, I wonder
What is mandel stress? How to use it?
Thanks.
I am teaching mechanics of materials to sophomore. However, our students do not have a separate static course. They get a some exposure to free body diagrams in particle dynamics. I am currently using the book by Gere and Goodno. But I found that both the teaching and learning experience were not good. Thanks a lot in advance for your suggestions!

Hi,
I'm trying to simulate a picture frame shear test using ABAQUS and I have landed up with some problems for which I haven't been able to find any solution from almost a week. Any help would be much appreciated!
So, here's the problem:
I have a fabric sheet of area 140mm x 140mm. The BC are as shown in the file bc.png.The bottom left corner is fixed and a displacement of UX = 40mm and UY = 40mm is applied on the top right corner node.
Hi all,
I have come across the two relations where aim to describe the isotropic hardening of a material
Power law:
R = Kεpn R is the variation in stress from initial yield, εp is the plastic strain where K is the strenght coefficient and n is the strain hardening exponent as observed in Ramberg Osgood equations.
Exponential law:
R = R∞ [1-e(-bεp)] where R∞ is the saturated value of the R variation, b is the rate at which the sauration is reached.
I have a question regarding the shape functions. Why the shape function is kept orthogonal to residue in Galerkin method? Looking forward to hearing from you all.

Hello everyone,
I am a doctorate student working with meshless methods for fluid flow. I would like to attend a summer school or workshops that can enrich my knowledge in FSI and meshless methods for FSI. I would really appreciate if anyone could recommend me a good school around Europe. As far as I have searched I was unable to find courses in the internet.
Thanks for your help,
Regards
Hi all
I am currently investigating Prager hardening room which is stated as the simplist linear kinematic hardening rule. I was wondering if anyone has worked with this model and if so if you have managed to identify how to determine the constant used for the back stress equation
dα =C * dεp ( this is epsilon dot p which is the equivalent plastic strain)
Please can you let me know how to determine the constant C from experimental results?
i have presented a new method for the first time to model of metal foams that subtracts stochastic cells from a desired volume and changes it to a foam.
i would like to know if there is any phd position for this?
thank u for your consideration :)
