The area of smart and functional materials, in particular fabrics with electric heating, attracts the attention of researchers.
Introduction High performance materials and technologies are fast developed for wearable electronics.
However, there are not differences between the mechanisms of heating fabrics – in all cases carbon fiber materials and electronic equipment are used for thermal comfort.
Eddy currents are to be found in any conducting materials that is subjected to a time-varying magnetic field [13].

Computer Simulation of Hot Stamping Process of DP Steel Car Bumper Chain Based on Dynaform Hanwu Liua, Zhaohui Liub, Huixiao Lic, Shaobo Pingd Sch. of Mechanical and Electrical Engineering, North China Institute of Science and Technology, Sanhe, Hebei, 065201, China ahanwu-liu@sohu.com, bzhaohuiliu@ncist.edu.cn, chuixiao998@qq.com, dhuakeshaobo@sina.com Keywords: DP high strength steel; Bumper chain; Hot stamping; Spring-back; Numerical simulation Abstract.
Along with the improvement of the strength performance, the duplex steel plate material needs to be adopted with hot stamping process for its deforming.
Taking the hot stamping forming technology of DP600 car bumper chain as the research object, this paper uses finite element method to analyze stress field, strain field, material thickness changes, and also the dimensional accuracy and spring-back of the final shape during the process of the bumper chain forming.
Fig.4 shows that the size of the spring-back before and after, and the measuring angle of spring-back is 135.114° before and 135.778° after then, and the size of spring-back angle is 0.664°, which is related to material properties, die clearance, die surface shape and friction coefficient such factors.
