发帖数: 97 | 1 seems like a simple question:
Here is a solid element in Lagrange Coordinate System(CS).
I know now the stress and strain of it in local CS(element CS):
SIGMA[xx],
SIGMA[yy],
SIGMA[zz],
SIGMA[xy],
SIGMA[yz],
SIGMA[xz],
...
also geometry and points' coordinates, etc.
How could i build up the transform matrix to know global stress and strain,
Still more parameters required?
any fortran or C++ rountine for example?I am confussed of the tensor
transforming, would like to be concerte.

几个星期了,也没人给点建议,
是不是太简单了,高手们都不斜一顾?
随便说点绳墨, 书啊,连接呀,都行啊

发帖数: 21 | 3 If you actually get the stresses and strains of each element by solving
the global system equation, I think you get the final results.Given the
stresses of each element, you can define the stresses of each node averaging
the stresses of elements that the node is associated with. To make the code
is
not difficult. There are other better ways to get smooth distribution of
stresses of each node.
