弹性动力学中一类系统的Riemann型初边值问题

Riemann type initial boundary value problem for a system in elastodynamics

Kayyunnapara Divya Joseph, P. A Dinesh

AI总结:

该研究延续此前弹性动力学非保守系统初边值问题的工作,突破原有数据限制,考虑一般Riemann型初边值数据,基于Riemann问题构建边值问题并显式构造解。

摘要:

本文是我们此前研究(文献[d1])的延续,该研究针对时空域x>0、t>0下弹性动力学中的非保守系统初边值问题展开。此前的研究假设初始数据与边界数据位于某一Riemann不变量的水平集上,而本文考虑一般的Riemann型初始与边界数据,基于Riemann问题构建边值问题,并显式构造出解。

英文摘要:

This paper is a continuation of our previous paper \cite{d1} on the initial boundary value problem for a nonconservative system appearing in elastodynamics in the space time domain $x>0,t>0$. There, the initial and boundary data were assumed to lie on the level sets of one of the Riemann invariants where as in this paper we consider the general initial and boundary data of Riemann type, formulate the boundary value problem based on the Riemann problem and construct explicitly the solution.
