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 :)
One PhD position is available immediately in the Department of Mechanical Engineering at Stony Brook University, NY, US. The research program focuses on the mechanics and multifunctional applications of 3D periodic composite materials including shape memory, acoustic/elastic wave propagation, and energy harvesting. The candidates with background in solid mechanics and finite element analysis are highly encouraged to apply.
