What is mechanics of materials ? • Mechanics of materials is a specialization within technical mechanics which studies how structures behave during loading • Structures: bridges, airplane wings, ships, paper, tennis racket, thigh bones,... • Behaviour: displacement, strain, stress, fracture, damage, vibration • Loading: static, variable, dynamic

v2 a v1

Studying Mechanics of Materials •

Strength based design and assessment: theoretical and experimental

•

Basic understanding of mechanics, mathematics, physics, data processing and materials

•

Numerical methods, vibrations, fracture, materials models, light-weight design, optimisation

Studying Mechanics of Materials •

Simulation and virtual prototyping needs to consider the mechanics and physical laws of how a component or system works: ”physics based engineering”

•

Mechanics brings realism to virtual reality

Mechanics of Materials courses Kul-49.4350 Fatigue of structures (5 cr) 24 + 12 (2 + 1) Time: period I-II in alternate years (may be taken during the first or second year of the programme) Instructor: Prof. Gary Marquis Contents: This course will cover principals of design to avoid fatigue failure of mechanical engineering components and structures. Topics introduction to fatigue, dynamic loading of structures, statistical aspects of fatigue, simple elastic-plastic deformation models for structural materials, integrated FE analysis and fatigue assessment for welded structures. The critical roles of stress concentrations, defects, surface finish and residual stresses on fatigue strength will be presented. Requirements: Exercises plus examination Prerequisites: BS level course in mechanics of materials or deformation and failure of materials. Literature: Course notes and R. I. Stephens et al., Metal Fatigue in Engineering, 2nd ed., Wiley Inter-Science Kul-49.4500 Continuum mechanics and Material Modelling (5 cr) 26 + 13 (2 + 1) Time: period I-II in alternate years (may be taken during the first or second year of the programme) Instructor: Dr. Kari Santaoja, senior lecturer Contents: Thermomechanics of internal variables is studied in order that the student will be capable of testing material models. The local field equations are derived from the global basic laws of nature. These field equations are the foundation for mechanics of materials and for thermomechanics. The Levenberg-Marquardt method for determination of the values for the material parameters is derived. The capability of this method is evaluated by examples. At the end of the course the implementation of material models into commercial finite element computer codes is studied by examples. After passing this course the student is familiar with the foundations of mechanics of materials, he/she can implement a material model in the ABAQUS finite element programme and he/she can determine the values of the parameters for a material model. Requirements: Examination and a voluntary assignment. Literature: Lecture notes in English. Prerequisites: BS level course in mechanics of materials or consent of instructor.
