Abstract : A failure theory for dry snow is based on the supposition that the nature of ice at the temperatures found in natural snow will cause stress concentration at a pore boundary to be minimized. External stresses will therefore tend to be uniformly distributed across constricted areas of solid substance. Failure is considered to occur when the available solid substance is stressed to its ultimate strength, taking into consideration the function of temperature and type of failure, i.e., tension, compression, or shear.
