聚变反应堆的第一壁结构承受由等离子体燃烧循环期间的不均匀温度分布和等离子体破坏期间的电磁感应冲击载荷引起的循环弯曲应力。这种载荷组合可能会导致塑性应变随循环的棘轮效应或增量累积。开发了弹塑性三杆模型来研究第一壁的棘轮行为。
First wall structures of fusion reactors are subjected to cyclic bending stresses caused by inhomogeneous temperature distribution during plasma burn cycles and by electromagnetically induced impact loads during plasma disruptions. Such a combination of loading can potentially lead to ratcheting or incremental accumulation of plastic strain with cycles. An elastic-plastic three-bar model is developed to investigate the ratcheting behavior of the first wall.
