For the purpose of analyzing compressive property of the human body, the compressive stress-strain relations were measured on the forearm, the upper arm and the thigh with the dynamic method. Assuming that the human body is a linear viscoelastic substance under specific conditions, the modulus of elasticity and the coefficient of viscosity were calculated. The modulus of elasticity and the coefficient of viscosity increased with compressive strain and varied according to the different points of the body.
The influence of garment restraint upon compressive properties of the human body was also estimated. Measurements were conducted before and after restraint on the upper arms of 3 subjects. After the restraint, a slight increase in the compressive hardness was observed, which would depend on the degree of restraint.
