Traditional approaches in contact mechanics demand complicated search algorithms at the interface between the contacting bodies. Recently, a new contact method based on the concept of a third medium has been developed, which overcomes the drawbacks of conventional contact mechanics techniques. This new scheme is based on a space filling mesh, in which the contacting bodies can move and interact. The...
Large deformation finite element analyses have been conducted to study the initial break-out resistance of on-bottom pipelines. Soil model that takes strain rate and soil remoulding into consideration was implemented. Results from detailed parametric study are presented in terms of failure envelopes in vertical-horizontal load space. The maximum vertical and horizontal resistance responses normalized...
