Postdoctoral postion in Computational Crystal Plasticity at RPI

Submitted by Suvranu De on

There is an immediate opening for a postdoctoral research position in the Advanced Computational Research Lab at RPI, Troy NY to work on Crystal Plasticity Finite Element Methods. Currently we are working on interesting advances in the areas of radiation damage and high strain rate loading conditions. Encouraged to apply are creative, self-motivated individuals with a sound baclkground in computational mechanics, CPFEM and materials science. RPI is home to the CCNI, one of the most powerful university-based supercomputational research facilities in the world.

 

Forced Vibration of Prismatic Beams

Submitted by CH von Kerczek on

Attached is a computer program, written in Scilab and easily convertible to Matlab, that computes and dsiplays vibrations of prismatic beams forced by a sinusoidal point force. One can impose a variety of boundary conditions, including ones with end masses, springs and dampers. I show several examples. This might be a useful pedagogical item to play around with.

I have similar programs and write-ups for free vibrations of Euler Bernoulli beams and Timshenko beams with variable properties. If any would be interested I would willing to post them too.

Cohesive Zone Modeling with Ansys multiphysic

Submitted by mystar_bkc10 on

Dear All !

Does anyone know how to creat Cohesive Zone in Ansys Multiphysics ? i am studying that but i havent created successfully, pls guide me step by step

I also make one contact in Ansys but, how to make it as Cohesive Zone ? i read in help, it guided me to use command  "TB and TBDATA". But the problem is i dont know when and where to use these commads.  If you know pls ponit me !

Thank so much !

 

buckling analysis of delaminated composite material

Submitted by saminathan krishnan on

i am doing final year mechanical engineering. i am doing project in analysis of

delaminated composite material.i dont know how to model a delaminated composite material in ansys.so kindly send the tutorial for that one to my mail-id.(saminathan.mkrishnan [at] gmail.com)

Carbon Nanohorn Reinforced Nanocomposites...

Submitted by Kmomeni on

I have formulated a shear-lag model for calculating the variation of stress along carbon nanohorns (CNHs), which are conical shaped wrapped carbon sheets, embedded in an epoxy matrix under axial loading.  I found that the stress distribution along the length of CNHs depends on the cone angle of these structures and maximum normal axial stress has a smaller value in CNHs compared to a carbon nanotube (CNT) with same cross-section as of the CNH's tip.  Furthermore, I read an article stating that synthesis of CNHs are easier compared to CNTs.  However, the only article I could f
