Hi Suo and other guys,

I am Chennakesava. I am new to this site. I have completed my Masters in Mechanical Engineering from Indian Institute of Technology, Kanpur, India. (IITK) . Year of study is 2006-08. My specialization is Solid Mechanics & Design. Right now am working in GE, India. I want to pursue doctoral degree in the field of Dynamics and Vibrations and related issues like, Rotor dynamics, Smart structures, MEMS, Nonlinear dynamics and Chaos. Its kind of a dream to me. 

Hello All
I am trying to read the text book Tensor analysis by IS Sokolnikoff and stuck in
chaper 1, there is some confusion in my mind regarding orthogonal transformations,
change of basis and and a transformation representing deformation of space.
Please bear with me if my confusions are unfounded.
1) Is is safe to say that transformation representing deformation of space acts on
vectors where as transformations representing the change of basis acts on
components?. (if yes then the following questions are resolved and need not be
looked)
2) Sokolnikoff builds up the reasoning for orthogonal transformations based on
deformation of space (i.e orthogonal transofrmations keep the length of vector

I'm working with multiple meshed items and attempting to cut them using the Instance boolean operation. My parts include parts I've sketched & meshed in Abaqus and a 3D object I imported from MIMICS (.inp file). When I attempt to selectively cut the instances that overlap, Abaqus failed. Any suggestions on the modeling of bone and implant with a reasonable fit in geometry?

Hi i want to model a compsoite shaft of glass/epoxy .i am having all material properties .i want to know how to model it .and in another case there is adhesives between the two.

Thanks,

   hii every one ... i am an  undergraduate student in mechanical enggineering . can any 1 suggest me a good project which includes  1.both computer oriented and also lab oriented project.

2.  also a  project in fatigue analysis.

Hello Everyone,

I have run a simple beam simulation of a cantilever pipe. I calcualted it with 8-Node brick elements, beam elements and hand calculation. At the up and low edge of the beam connection to the wall, I got maximum stress values as expected. While the beam and hand calculation results are similar  (40 MPa), brick element calculation is higher. (50Mpa). Interestingly the finer the mesh of brick elements the higher the stress values. I couldnt figure out the reason of it. Can any one say a comment?

 Thanks in advance

thanks a lot

Iam beginner in ansys, so i have problem in enter the steps of cyclic load to a plate as solved in ansys to get the deformation with time curve.

can any help me??
