MHA042   Material mechanics


In order to be eligible for a second cycle course the applicant needs to fulfil the general and specific entry requirements of the programme that owns the course. (If the second cycle course is owned by a first cycle programme, second cycle entry requirements apply.)
Exemption from the eligibility requirement: Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling these requirements.

Course specific prerequisites

Basic courses in mechanics and strength of materials equivalent to the course offered by the Mechanical Engineering program, TKMAS, are required. Mathematics, in particular, linear algebra, calculus , and numerical methods. A basic course in FEM is strongly recommended but not a hard prerequisite for attendance to the course.


Material mechanics is a key ingredient in the finite element modeling of advanced components, like engines, automotive and civil engineering structures etc. In fact, many engineering materials deviate from behaving perfectly elastic under service conditions. This occurs whether the loading is sustained, time-dependent of impact dynamic character, quasi-static with cyclic variation or due to elevated temperature. Typically, the material response becomes non-linear due to the development of inelastic deformations, which may be represented as elastic-plastic and/or viscous elastic-plastic, depending on the ambient temperature and the type of mechanical load. One purpose of the course is to develop fundamental mathematical model concepts, also known as constitutive modeling, that describe the non-linear stress-strain response of the material under consideration. Examples of constitutive theories are those of elasticity, elasto-plasticity and elasto-viscoplasticity, which may be combined to model quite complex physically observed material behavior in conjunction with monotonic and cyclic loading. In fact, the observed behavior may be more or less well represented by the modeling concepts, thereby involving additional material parameters as compared to the perfectly elastic case. Special procedures of how to calibrate these parameters for a given loading are also outlined in the course. Parallel with the conceptual model developments, another purpose of the course is to advance the computational handling of the constitutive models to facilitate the proper model calibration and to outline the link to finite element analysis of real world components. In this context, the finite element based analysis of a structure is emphasized with material mechanics being the heart of the modeling.

Learning outcomes (after completion of the course the student should be able to)

  • Describe, outline and implement the elasto-plastic stress-strain relation in the multiaxial stress-strain context based on the von Mises yield condition.
  • Formulate and implement the non-linear finite element analysis of elasto-plastic response with respect to multiaxial stress-strain states.
  • Formulate and implement calibration of material parameters based on experimental data based on concepts of optimization.
  • Explain the strong links between material modeling of observed physical phenomena, the fundamental principles of continuum mechanics, and the computational aspects (related to model calibration and finite element formulation) of the modeling.
