Fracture toughness of wet and dry particulate materials comprised of colloidal sized particles: role of plastic deformation.

This work demonstrates a method of measuring the fracture toughness of particulate materials comprised of colloidal sized particles over a wide range of saturation. Diametral compression of cylinders containing flaws of controlled length was used to measure the mode I fracture toughness. The effect of degree of saturation on the fracture toughness of slip… CONTINUE READING
