WOOD FRACTURE PATTERN DURING THE WATER DESORPTION PROCESS

Wood is a hygroscopic material and its mechanical properties change with moisture content below the fiber saturation point. Fracture characteristic is one of most important mechanical properties of wood and often is taken as an important safety design factor for wood as an engineered structural mate...
