Abstract

The mechanical properties of spruce were studied at various temperatures ranging from-190 C to + 250 C. Diagrams are presented to show how maximum tensile stress, strain. modulus of elasticity. and work-to-maximum load changes as a function of temperature. The fracture energy reaches a maximum value around-40 C and is reduced to a low level at 150 C and over. Tensile stress increases in a linear manner with a decrease in temperature reaching a theoretical maximum at zero Kelvin degree.
