Failure Mechanism of Lignocellulosic Material under Ezplosive Load
When lignocellulosic material is subjected to explosive loading, the explosive wave and gas generate the stresses in free interface: tensile stress, pressure stress and sheer stress. The damaged area of wood chips is clearly divided into three zones: dilatation zone, rupture zone and compaction zone. It is the key factor to get a hold of the mechanism of dilatation in the complicated stress condition. By using the information observed from Scanning Electron Microscopy (SEM),failure model of lignocellulosic material in the three zones under explosive load is discussed based on the principals of the explosive dynamics and fracture mechanics.
