Usually, the position of points in Mohr's circle is attributed to a sign convetion related to shear stresses. It is shown that points in the circle related to shear stresses generating a clockwise moment are in the upper half of the circle as a consequence of the position of principal directions, not due to a convention. I hope this note could help to explain better the use of Mohr's circle in plane stress states.
Dear all,
On Thursday 28th and Friday 29th of October 2010, we will organise a course on using the CONTACT software at Delft University of Technology in the Netherlands.
The aims of the course are:
I would like to know how to write a stiffness matrix for a bar under torsional load. I would like to write a code in C++ to do this. I would like to know of any material regarding this.
Thanks in advance
With Br

Do you want to learn the boundary element method (BEM) and the latest fast solution methods from the experts around the world? If yes, come and attend the workshop on the BEM in September.
Hi everybody
Im working on a project about Finite element modeling of Contact. Im not allowed to use contact solving feature of ANSYS and i should use its Macro Programming. in this case i should read stiffness matrix from ansys, add some row and column to it and input it back to ansys and solve it.
I have two problem with this, first i dont know how to input modiffied stiffness matrix back to ANSYS..
Dear all,
