СПОСОБ ОПРЕДЕЛЕНИЯ ФОРМОВОЧНЫХ СВОЙСТВ

摘要

FIELD: investigating or analyzing materials. ^ SUBSTANCE: method comprises deforming the specimen and determining the variation of the angle between the threads of warp and weft until the diagonal fold occurs. The specimen is sheared so that the stretching strain of the threads is absent. During the shearing, the values of variations of the angle and appropriate forces are determined. ^ EFFECT: enhanced reliability. ^ 3 dwg, 1 tbl
