strain-hardening material
解釋
應變硬化材料-
While cyclic deformation experiment under constant strain control is performed in 400, the material shows the continuous hardening until cyclic invalidation. ( 3 ) back stress attained by kwl " s method is used to analyse the bauschinger effect during an incremental step cyclic test and cyclic deformation test under constant strain control, it is shown that back stress increases with increasing plastic strain and the numbers of cycle, and the back stress is uniform, regardless of tension or compression conditions. ( 4 ) as far as recrystallized zircaloy - 4 plate is concerned, the back stress in transverse direction is higher than that in rolling direction due to the higher schmid factor in rolling direction
對于再結晶狀態的zr一4合金板材試樣來說， t方向（橫向）試樣的背應力要高於r方向（軋制方向）的背應力，原因在於r方向的schmid因子高於t方向的schmid因子; 400下， zr一4合金的背應力要明顯低於室溫下的背應力;含氫200pg / g的zr一4合金的背應力大小與無滲氫的zr一4合金背應力相比，無明顯區別;固溶處理后， zr一4合金的背應力大小發生了變化，在較高塑性應變下，背應力均高於固溶處理前的背應力。 -
Based on the damage evolution formation depicted by kachanov of brittle materials in unitary stress state, in this dissertation, the constitutive equation of nonlinear damage material is given, macroscopically, on the assumption that damage variable is exponential relation to strain, d = ( gy i k ) ", where g is the shear module, k is the damage module and the y is the effective strain, d is damage variable and n is hardening exponent
在kachanov描述的一維應力狀態下的脆性材料的損傷演化模型的基礎上，文中給出非線性損傷材料的本構方程，唯象地假設損傷變量與應變成冪次關系， d ~ * = （ g / k ） ~ n ，其中g為剪切模量， k為損傷模量，為有效應變因子， d為損傷變量， n為硬化指數。
