Experimental study on crack initiation and propagation of wood with LT-type crack using digital image correlation (DIC) technique and acoustic emission (AE)

Monitoring the cracks initiation and propagation of construction materials, as well as determining the fracture process zone, constitute two key factors to understand the damage mechanism of materials in order to control the risk of material degradation and failure. This paper demonstrates the results of a laboratory static test designed to investigate the in situ monitoring of crack tip growth in wood. LT-type single-edge notched specimens made...
