Learn to analyse nonlinear material behaviour and large deformations using the finite element method. Apply models in Abaqus to assess materials, forming processes and structures.
Nonlinear Solid Mechanics prepares you to perform nonlinear finite element analyses involving large deformations and nonlinear material behaviour. Although many structures are designed to operate within the linear range, nonlinear analysis is essential when components undergo large deformations, materials deform permanently or structures are subjected to loads beyond their normal operating conditions.
In this course, you learn how large deformations affect the definitions of stress and strain and how nonlinear material behaviour can be described mathematically. You study hyperelastic models for different materials, elastoplastic models for metals and continuum damage models for material failure. The course also covers yield functions, isotropic and kinematic hardening, plastic instability and fracture. You apply this knowledge in finite element simulations of forming processes using Abaqus. This helps you understand, analyse and evaluate the behaviour of materials and structures in applications such as rubber seals, bulk forming, sheet metal forming and structural overload.
This is a regular master’s course in which both students and professionals can participate. The course combines lectures on campus, self-study and supervised practical assignments. The lectures introduce deformation kinematics, stress and strain measures, hyperelasticity, metal plasticity, hardening, failure and continuum damage. Participants also learn how numerical algorithms for plasticity can be implemented in a finite element framework.
The practical assignments focus on finite element simulations that participants complete in groups of two under supervision. Using Abaqus, participants design and simulate a forming process for a product and investigate the plastic behaviour of metal during processes such as deep drawing. The assignments provide opportunities to apply the theory, analyse simulation results and receive support and feedback.
Details and assessment:
This course is intended for professionals who want to deepen their understanding of nonlinear material behaviour and nonlinear finite element analysis. Typical profiles include mechanical engineers, CAE and FEM engineers, simulation specialists, forming-process engineers, materials engineers, structural analysts and R&D professionals working with metals, rubber-like materials, manufacturing processes or structural safety.
Participants are expected to have basic knowledge of the finite element method. Prior completion of Advanced Topics in Finite Element Method (201900091), or equivalent knowledge, is recommended. Knowledge of Linear Solid Mechanics is helpful, but not strictly required.
If you successfully complete the course, you will receive a microcredential. This microcredential is a digital record confirming that you have passed the assessment components of the regular master’s course and achieved the corresponding learning outcomes.
You may also participate without completing the assessments. If you choose this option, or do not pass all assessment components, you will receive a digital certificate of participation.
