Simulation of Material’s Damage and Safety Parameters’Variation by Image Processing Method

Material＇s crack always starts from the most non-homogeneous position while it is under exterior force. By combining image＇s ightness and element＇s strength, an artificial material had been made up and its breakage process is simulated and the probable crack has been worked out through edge detection method. The further process of the image proves the rule of displacement, damage and fractal variation that the value of damage and fractal increases with the growth of the crack while the augment rates are different. And the displacement orientation is consistent with that of lightness gradient, which is meaningful and revelatory to discover the law of breakage.
