abstract introduction: heat stress risk assessment, as a harmful agent at workplace, is essential for controlling heat strain and heat stress effectively. this study is concerned with the relationship between physiological strain index (psi) and wet bulb globe temperature index (wbgt) in women in the climate chamber . methods: this experimental study was carried out on 36 healthy females in sit...

The stress-strain relationship of frozen soil is important to indicate the strength of frozen soils in use. According to traditional mechanics, the stress-strain relationship in geomaterials is a smooth curve. However, some studies have shown that the real stress-strain curves of geomaterials, such as concrete, rock and frozen soil, are step-like and that they have fractal characteristics. Ther...

This paper proposes a method to calculate the uniaxial stress /strain relationship of polycrystalline Fe /Pd, which has a martensite structure produced by cooling. Strain is caused by changes in the fractions of the three Bain corresponding variants which form the martensite structure within each grain. Internal stress and elastic energy are accumulated as straining proceeds and are caused by d...
