Seismic Analysis

Base Shear and Overturning moment

Hi

     I am doing seismic analysis of Fluid filled cylindrical steel tanks using FEM. In this analysis I m supposed to find Base Shear and Overturning moment. Steel tank is thin shell and is flexible. For the complete loading of the shell I have its stress field i.e I have Nxx, Nxy, Nyy, Mxx, Mxy, Myy components of the thin shells middle surface. They are per unit length. Using these components how I can find Base Shear and OTM?

      Any reference/suggestion for this study....

Thanks in advance

Micro Analysis of Composites in ansys

micro analysis of composites using Ansys

 Hi everybody, i am Ravikumar doing M. Tech. project on multi scale analysis of composites.

I gave the input as nodal displacements and different material properties for glass and resin. I applied all the normal stresses and shear stresses on the micro scale model which is of hexagonal array  structure. (i.e., one circular fiber at the centre and quarter fibers at the four corners of the model and the remaining portion is filled up by resin).

Teaching Engineering Thermodynamics to Undergraduate Students

I have just volunteered to teach engineering thermodynamics to undergraduates in the Fall semester of 2011.  The students will be from all fields of engineering, primarily mechanical engineering, environmental engineering, and bioengineering.  I have never taught this course before, and would love to hear from you about your experience, either as a student or as a teacher. 

Here is what I have found from the website about the course.

How to simulate torsion of cylinder in ANSYS?

Submitted by sspadhee on

I want to model torsion of a homogeneous hollow cylinder in ANSYS. I changed to cylindric coordinate system also. But each time I run the program  the result is that of bending. I have attached the mac file and output file for reference. Please advise.
