非线性Pochhammer-Chree方程的有限元方法误差估计
The Finite Element Method Error Estimates for Nonlinear Pochhammer-Chree Equation
【摘要】 用有限元方法研究了弹性杆纵向形变方程:utt-uttxx-uxx-1p(up)xx=0的初边值问题,构造了半离散和全离散两种格式,并在两种格式下均得到了H1模最优阶误差估计.
【Abstract】 An initial-boundary value problem of the nonlinear Pochhammer-Chree equation with the finite element method is studied in this paper.A semi-discrete and a full discrete schemes are presented,and the optimal order error estimates in H1 norms are obtained.
