shear hardening 中文意思是什麼
shear hardening
解釋
切變硬化-
Supposed the two nonreversible deformations both obey the drucker law, the plastic loading function was established based on experimental data and the plastic work was used as hardening parameter supposed loess damage is mostly due to shear and the damage potential function has the same form of the equivalent plastic strain line in the plastic part, the damage potential function was gained by fitting the test data
假定兩類不可逆變形都服從drucker公設，根據試驗數據確定以塑性功為硬化參數的塑性加載函數。認為損傷主要由於剪切產生，假定損傷勢函數與塑性部分的塑性剪應變等值線具有相同的形式，通過試驗數據擬合得到損傷勢函數，然後根據損傷理論推導建立q1黃土的彈塑性損傷本構模型。 -
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。
