Course content

Advanced materials mechanics (constitutive relations for large plastic deformations, damage and fracture criteria, explicit finite element methods), impact and energy absorption (elastic and plastic impacts, elastic and plastic stress-wave theory, energy absorbing components and systems), penetration mechanics (empirical, analytical and numerical methods) and blast loading against structures(empirical, analytical and numerical methods).

Learning outcome

Impact Mechanics is an advanced course in applied mechanics for students with specialization in structural engineering and/or industrial mechanics at MTBYGG, MTING and MTPROD. The course covers theories for materials and structures subjected to transient dynamic loads such as impact, penetration and explosion. A key part of the course will be devoted to applied use of analytical methods in combination with explicit non-linear finite element analysis for solving this kind of problems.

Impact Mechanics has the following learning goals:
The candidate should have knowledge of:
- The behaviour of materials and components subjected to impact, penetration and blast loading
- Constitutive relations and fracture criteria for materials subjected to dynamic loads
- Explicit non-linear finite element analysis of large plastic deformations
- Impact loading and stress-wave theory
- Energy absorption in materials and components
- Empirical, analytical and numerical models for penetration and blast loading

The candidate should know how to:
- Choose empirical/analytical/numerical models to calculate the behaviour of materials and components subjected to transient dynamic loads
- Identify material parameters in mathematical models from laboratory experiments
- Perform explicit finite element simulations of materials, components and structures subjected to impact loading

General competence:
The candidate should acquire skills in:
- Mathematical modelling of materials for large plastic deformations
- Parameter identification from laboratory experiments
- Establish models for impact, penetration and blast loading
- Perform explicit finite element analysis of transient dynamic problems

Learning methods and activities

Lectures, guest lectures and case studies. All case studies are required to be given access to the exam. Lectures are given in English when students who do not speak Norwegian take the course. If the lectures are given in English, the examination paper will only be given in English. The students’ answers can be in Norwegian or English.

Compulsory assignments

  • Labratory exercises

Further on evaluation

At resit exams, the exam may be changed from written to oral.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.

Course materials

Lecture notes. Supporting literature: Various books/articles in Impact Mechanics.
