Design Method Using Response Surface Model for CFRP Corrugated Structure under Quasistatic Crushing

The development of a carbon-fiber-reinforced plastic (CFRP) part is carried out by utilizing many experimental results in deciding the design. For this reason, the development period of a CFRP structure is long and an obstacle for commercialization. In this paper, multiple regression analysis is use...
