Material Failure Criteria for FE-solvers Users, Theories of elastic failure-Forming limit diagram-Failure criteria in simulation software.
Course Description
This course introduces a comprehensive discussion for material failure criteria
The course consists of six lectures.
The course is thought to be helpful for those who uses FE-solvers for the simulation of various metal forming processes.
The theoretical background is combined with practical implementation by the end of the course.
[Lec1 and Lec2]: Stress strain curve, true and engineering data, various types of stresses, and theories of elastic failure.
[Lec3 to Lec6]: Forming limit diagram, major and minor strain, Nakajima test, ISO12004, data interpretation, Application on deep drawing process simulation on Lsdyna.
Through those lectures, the failure criteria suitable for each case is introduced.
As one of the targets of this course is to qualify the attendees to be professional users for simulation software, the last lecture focuses on how the forming limit diagram can be used to evaluate a deep drawing process simulated on one of the famous FE-solvers which is Lsdyna. Other graphs such as formability and triaxility are introduced.
Useful material is attached with each lecture for students to help them to cope with the recording.
The course in general is integrated to our course in Udemy titles “Mechanical design a comprehensive course” and also “Ansys explicit dynamics course”, which is prepared to be in English soon.
