表 1 刚度等效预测施加的6种周期性位移边界条件

Table 1 Six kinds of boundary conditions when stiffness equivalent predicting

Conditions	Strain loads	Forced displacement applied
Case 1	$\{ε_{x} 0 0 0 0 0\}$	$u_{x}^{x = W_{x}} = W_{x}; u_{x}^{x = 0} = u_{y} = u_{z} = 0$
Case 2	$\{0 ε_{y} 0 0 0 0\}$	$u_{y}^{y = W_{y}} = W_{y}; u_{x} = u_{y}^{y = 0} = u_{z} = 0$
Case 3	$\{0 0 ε_{z} 0 0 0\}$	$u_{z}^{z = W_{z}} = W_{z}; u_{y} = u_{y} = u_{z}^{z = 0} = 0$
Case 4	$\{0 0 0 γ_{xy} 0 0\}$	$u_{x}^{y = W_{y}} = W_{y}; u_{x}^{y = 0} = u_{y} = u_{z} = 0$
Case 5	$\{0 0 0 0 γ_{yz} 0\}$	$u_{y}^{z = W_{z}} = W_{z}; u_{x} = u_{y}^{z = 0} = u_{z} = 0$
Case 6	$\{0 0 0 0 0 γ_{zx}\}$	$u_{z}^{x = W_{x}} = W_{x}; u_{y} = u_{y} = u_{z}^{x = 0} = 0$
