A little dizzy? Let’s talk about it in a popular way. For example, a person was very thin before and bought a pair of L-size jeans. However, after a year, he became very fat. When he wore these jeans again, he would feel that his trousers were too tight because he was fat and his trousers didn’t change. At this time, there was a strong force between his body and his trousers. If he used too much force, it was easy to tear them, This destructive force is the effect of residual stress. From the perspective of energy work, when the external force causes the plastic deformation of the object, it will cause the internal deformation of the object, thus accumulating part of the energy; When the external force is eliminated, the energy with uneven internal stress distribution will be released. If the brittleness of the object is low, it will deform slowly, and if the brittleness is high, it will form cracks.<\/p>\n\n\n\n
