| Abstract: | ractal dimension of impact fracture surfaces of PVC at differenttesting temperture were investigated by means of secondary electron line scanning.Experimental results shows that the impact strenth rises linearly with the increaseof fractal dimension.The fractal dimension on crack growth region decreases butthat on final fracture region increases with the testing temperature decreasing. |
