Simulation of Residual Stress in Cold Working of Flat Spiral Springs ZhanHua Li1, a, JingTao Han1,b, Jing Cheng1, c , Shuai Ji1, d 1School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing, China, 100083 ali_zhanhua@163.com,bhanjt@ustb.edu.cn, cchengjing_ustb@163.com, dcarven0910@sina.com Keywords: Flat spiral springs, Residual stress, Finite element analysis Abstract.
The flat spiral spring is a structure consisting of a wire coiled into a spiral lying in a plane, which can be fabricated by wounding elongated materials with constant section into a spiral shape[1].
The interface part of spiral is connected with the strip material, which is binding style in ABAQUS.
The material of the spring strip is 65Mn in the simulation.

Lithium titanate(Li2TiO3) in form of packed pebble bed is promising concept for breeder material in the fusion reactor blanket, and worldwide efforts have been dedicated to its R&D in the last two decade.
There are two major material-form options for the tritium which are breeder sintered block and pebble bed.
So the pebble bed was proposed as a material form for the tritium breeders in fusion blankets.
