dc.description.abstract | Woven carbon fiber-reinforced plastics (CFRP) has been widely used in automotive industries due to its superior strength and stiffness to weight ratio. However, it is hard to predict mechanical behavior of woven CFRP because of its complex structure, which increases the engineering cost to design it. In this study, mechanical behavior of woven CFRP was predicted by deep neural network (DNN) models. Dataset was made by multiscale simulation depending on structures (yarn width, space, height and volume fraction) and mechanical properties of fiber and matrix. Structures and mechanical properties were used as input of DNN, and stressstrain behavior was used as output of DNN. For cost-effective train, the number of points on stress-strain curve was reduced by principal component analysis (PCA) to reduce a model size and computing time. The range of mechanical properties of constituents and dimensions for geometric modeling is selected in consideration of that of commercial products. Finally, the prediction of stressstrain curve by DNN only takes 2 seconds which is far shorter than conventional FEM based simulation, which accompanying modeling, meshing, calculation, and etc. The predicted results are presented and are in good agreement with experimental and simulation result. | - |
