Automatic Generation of Weaves for the CAM of 2D and 3D Woven Textile Structures.

A new computer aided manufacturing (CAM) process uses two dimensional weave matrixes to generate two and three dimensional woven fabrics automatically. The CAM system groups the two dimensional weaves into regular and ireegular weaves, allowing the system to treat them separately. When the parameters of a type of weave are specified, the ..

Damage Growth in Prestressed Plain Weave Fabrics.

A simplified micromechanical approach developed a mathematical model to predict damage growth in prestressed plain weave fabrics near sites where yarns were broken. Stress concentration in the yarns adjacent to the breaks was a function of increasing load. An evaluation of the load distribution around the region of damage included a deter..
