Fabric mechanics refers to the study of the mechanics of woven fabrics pertaining to its structural dimension in the space lattice. Fabric mechanics forms a core of the mechanotextile technology where technological advancements are being employed to study and design new and improved varieties of fabrics. Now-a-days softwares are being employed to carry out the function. The general energy analysis of material mechanics by means of best management given in an exceedingly previous publication is applied to the woven-fabric structure for deformations whereby the yarns stay within the same plane.
