A theoretical method to analyse the residual stress in machined surfacewhen pre-stressed machining is presented.
利用热弹塑性力学理论和有限元方法,从理论上计算已加工表面残余应力,讨论预应力加工条件对加工表面残余应力的影响,从而为表面残余应力的控制提供了理论依据。
6) pre-compressive stress
预加压应力
1.
The effects of microamount additions of RE(Tb, Sm) on the martensitic transition and the magnetic-field-induced strains of highly textured polycrystalline Ni-Mn-Ga alloys were investigated,and the effects of pre-compressive stress on the magnetic-field-induced strains of the alloys were studied especially.
研究了稀土元素Tb和Sm对Ni-Mn-Ga磁性形状记忆合金的马氏体相变及磁致应变的影响,并着重研究了预加压应力对合金磁致应变的影响作用。
补充资料:预应力
分子式:
CAS号:
性质:试验中试样所受到的预加的恒定静态应力,单位为Pa。在生热性疲劳试验中,如固特里奇屈挠试验中,一般都施加一恒定预应力,使试样产生一静态变形,再叠加一周期压缩变形进行试验,通常预应力的大小会影响试样的疲劳寿命,预应力越大,则试样寿命会越明显缩短。也有的先施加一静态压缩变形,再叠加周期性剪切变形进行试验。
