板材模压复合材料(SMC)在工业中的应用,特别是在汽车制造业方面有很大的潜力。有些汽车零部件,如车门、车盖和车体都容易受到硬物撞击而损伤。所以进行动力响应分析、损伤的标征和预测,以及剩余强度的预报是十分必要的。 The application of sheet metal composites (SMC) in the industry, especially in the automotive industry, has great potential. Some car parts, such as doors, hoods and bodywork, are easily damaged by hard objects. Therefore, dynamic response analysis, damage sign and prediction, as well as the prediction of residual strength is very necessary.
