Fracture mechanics and its application to wood / Mustafa Mohamad
Using fracture mechanics one can predict the strength of wood that contains knots, notches, cracks and other discontinuities. The author undertakes to introduce the reader the fundamentals of fracture mechanics and its application to wood incorporating a small-scale experiment using the standard tes...
