A platform for research: civil engineering, architecture and urbanism
All materials are viscoelastic in nature due to the existence of flaws. Such flaws are inherent or produced in manufacturing procedures. This introduces a size and a time dependence of the strength properties. A stochastic theory based on the minimum volumetric and distortion strain is derived to consider both brittle and ductile failures. Such a theory includes both the size and the time dependence as well as the random variation. The theory is general and can be applied in creep, fracture mechanics and fatigue for any material. Parameter estimates are given for steel, concrete and wood. (Copyright (c) Swedish Council for Building Research, Stockholm 1987.)
