Performance stability of stalks composites is poor, the materials performance can not be guaranteed perfectly safe.
NDT is a method under the premise of without damaging the performance of the tested object, which applies a variety of physical principles and chemical phenomena, gets effective detection of the materials properties, the integrity, continuity, security reliability and certain physical performance of materials can be evaluated [1].
The reason was the material substances (stalk cell wall) in the mean unit volume increased with the density increase of soybean stalks particleboard, more substantial materials can enhance the resistance to the external damage.

For brittle material, the evolution of the interface Γo separating the undamaged material d = 0 to the damaged one d = 1 have been studied in a framework based on an energetical description ([4, 11]).
The initial material and the damaged material are separated by a surface Γo.
