16th SHORT COURSE ON COMPUTATIONAL PLASTICITY

Barcelona, 6-7 September 2021

Objectives

The 16th edition of the COMPLAS course on computational plasticity aims at providing a comprehensive view of the theory of plasticity for the computational solution of problems in engineering and applied sciences. The theoretical lectures are complemented with others presenting applications of computational plasticity to a number of practical problems.

In-person and online participation

Attendance to the course can be either in in-person mode or in on-line mode. The course lectures will be streamed in syncronous fashion to on-line partitipants. Details of the on-line mode will be provided at a later stage.
Both the in-person and the on-line options are compatible with the participation in the COMPLAS XVI conference.
