Deformation measurement of special clothing model using the moire method

Deformation of the special clothing during use was analyzed by studying the mechanical properties and the deformation characteristics of the clothing material with the clothing divided into the trunk and the four limbs. Only the in plane deformation distribution of the trunk surface was analyzed, while the curved deformation of the four limbs was analyzed. The deformation characteristics of the trunk surface and the four limbs were used to develop a unidirectional tensile model and a thin cylinderical model for experiments with the strains measured using the moire method. The experiments have shown that the method can conveniently and accurately measure two kinds of deformation. The experimental results can be used for deformation analysis of the special clothing to ensure safety.
