TexMath is a modular software program which enables simulations of multi-scale problems of solid mechanics for specific textile applications. Tools are based on algorithms for dimension reduction and homogenization.
Periodic textile structures with complex bonds can be created with the structure generator (MeshUp). Another component called FiberFEM then computes the effective mechanical properties of recurring structures under infinitesimal strains. Alternatively, the FISFT component can be used for long stretching and is ideal for simulations of complex load scenarios on textiles or even while in production, such as knitting.
Each of these tools interfaces with the others as well as with GeoDict, if required for additional simulations of fluid mechanics, for example, to compute the fabric’s permeability in each stretched state. By means of the interface with FeelMath, the possibility of a detailed, three-dimensional mechanical simulation of individual yarns is presented, which allows the strength and durability of specific yarns to be examined at their contact nodes within the fabric.
