Abstract:This paper is concerned with the study of the stability of numerical methods for a class of second order delay differential equations. By using the boundary locus method, the delay-dependent stability region of the trapezium rule is analyzed and its boundary is found. Then the relationship between analytical and numerical stability regions is identified and it is proved theoretically that the trapezium rule can completely preserve the delay-dependent stability for the considered set of test problems.
Keywords:trapezium rule   delay-dependent stability   second order delay differential equations
