A continuum damage model is proposed to predict the intralaminar progressive failure of CFRP laminates based on the modified Puck's theory. Puck's failure criteria, with consideration of the in situ strength effect, are employed to evaluate the onset of intralaminar failure including fiber fracture and inter-fiber fracture. After damage initiation, a bilinear constitutive relation is used ...

In order to reduce the power consumption of the ball mill, the feed particle size of the ore can be reduced. Therefore, the product particle size of the ore is required to be small, that is, "more crushing and less grinding" should be achieved. 3. Control the filling rate of steel ball. When the rotation speed of the ball mill reaches a certain ...
