Convergence results of a heterogeneous asynchronous newmark time integrators

This paper is concerned with the convergence analysis of PH heterogeneous asynchronous time integrators algorithm, proposed by Prakash and Hjelmstad [ Int. J. Numer. Methods Eng. 61 (2004) 2183–2204], devoted to transient dynamic problems for structural analysis. According method, discretization performed using well-known Newmark schemes, where step ratio, i.e. , ratio macro micro step, two subdomains separated an interface a positive integer. The restricted linear simplification. We show that L ∞ -uniform approximated solutions achieved taking into account damping terms suitable regularities on load terms. shall also give some error estimates method.
