基于应变张量的单轴性假设，提出了平面内细长直梁的大变形理论。协调条件的积分给出了梁横截面上应变张量轴向分量的抛物线变化。运动学方程的积分给出了横截面上位移分量的线性变化。平衡方程写在变形的配置和数值求解线弹性悬臂梁，受到集中或分布保守和非保守载荷。
A theory of large deformations of straight slender in-plane beam is presented, based on the assumption of uniaxiality of the strain tensor. The integration of the compatibility conditions gives the parabolic variation of the axial component of the strain tensor over the cross-section of the beam. The integration of the kinematic equations gives linear variation of the displacement components over the cross-section. The equilibrium equations are written on a deformed configuration and numerically solved for linear elastic cantilever, subjected to concentrated or distributed conservative and nonconservative loads.
