   报告主要内容:

  Ship collisions can result in loss of human lives and severe environmental damages. Collision simulations of ship structures are performed to evaluate preliminary and detailed designs. These simulations need to define the nonlinear behaviour of the material including strain hardening and failure. This seminar reviews the mathematical expressions for the flow curve that have been adopted to evaluate the strength of ship structures. The review includes the combined material relation; the failure due to material rupture is assessed through simulations of tension tests using different failure strain and mesh densities.

  报告人简介:

  Dr. Richard Villavicencio is a Senior Specialist in the Structures Research & Procedures team of Lloyds Register Marine & Offshore, coordinating the development of software tools for fatigue design assessments. Obtained a PhD degree in Naval Architecture and Marine Engineering from the University of Lisbon on the responses of marine structures to impact loading and conducted post-doctoral research on the design of crashworthy ship structures. The academic research resulted in numerous publications in peer-reviewed journals and conference proceedings. Currently participating in research on accidental loads due to ship collisions with application to Tanker Vessels and Gas Ships. A member of the International Ship and Offshore Structures Congress (ISSC) - Committee III.2 Fatigue and Fracture. Industrial mentor of Master and PhD students and lead trainer to personnel from ship design/appraisal offices.
