Model
The default is the simplest woven composite material. When editing the material properties, it is found that the matrix properties are set normally and it is an isotropic material, but the material properties of the yarn do not have elastic properties settings.
After exporting the inp file and importing it into ABAQUS, you can actually see that there are two materials, and the yarn also has attributes.
Modifying properties in ABAQUS is slow on the one hand and needs to be changed every time on the other hand. Therefore, consider exporting inp and modifying the material properties of inp first.
