Historically, accurate and robust numerical modeling of various contact interactions has posed significant challenges to the engineering community. In this presentation, we will discuss the development of general contact for the commercial implicit finite element software Abaqus/Standard. In particular, we will focus on philosophical and technical aspects related to making general contact highly-automated, robust, and accurate for a wide range of contact problems. Overviews of underlying formulations (i.e., surface-to-surface, edge-to-surface, and edge-to-edge contact formulations) used by general contact together with relevant examples will be presented. As time permits, aspects related to stabilization and contact stress accuracy will be discussed.
