Problem Description
In this example, failure index, strength ratio, and failure envelope of a 3D orthogonal woven plate are predicted using MSG failure functions. For computing failure index and strength ratio, an external load can be defined. Since we are using MSG plate model, the load is in terms of plate stress resultants such as {N11, N22, 2N12, M11, M22, 2M12}. Therefore, the corresponding strength constants are also in terms of plate stress resultants. For the failure envelope analysis, a biaxial loading case is assumed with N11:N22 = 1:1.
Solution Procedure
* step 1
The SG of an 3D orthogonal woven plate is first created as shown in the figure below, which is created using the 3D weave function in texgen4sc with the default parameters.
* step 2
- step 3
