摘要
本文从理论上推导出变薄系数η,从而确定了变薄量△=ηt_0,认为中性层的位置应在p_0=(K+0.5-0.5η)t_0。文中还从理论上推导出展开长度系数α,并确定展开长度公式L=at_0,它可简化计算,且精确度高。
The thinning coefficient η is determined through theoretical deduction with the thinning amount Δ=ηt_0 defined. It is assumed that the position of the neutral layer (ρ_0) should be at (K+0.5-0.5η)t_0. Besides, the lengthening coefficient α is determined through theoretical deduction with the equation for lengthening defined as L=αt_0, which can help simplify the calculating process and enhance the accuracy of calculating.
