LMU111 Strength of materials, advanced course lp1 HT21 (7.5 hp). The course is offered by the department of Industrial and Materials Science. Detailed course-pm.
The course advances your knowledge in solid and structural mechanics. Emphasis is placed on the modeling of multiaxial stress and strain states in 2D structures and structural stability. 2D structures considered are elastic plane strain, plane stress and axisymmetric sheets. Also plate and technical shell theories are presented. The necessary skills required to compute limit loads of simplified beam structures and stresses and deformations of various 2D geometries are provided.

These primers are offered as pdf-files, free of charge under the module ”text books”.
The course comprises 32 hours of lectures, L1-L16 in the detailed course outline, 34 hours of tutorials, E1-E17, and 14 hours of scheduled computer assignment classes, C1-C7 in the course-pm.
The theoretical and computational basis of the considered solid mechanics is outlined in the lectures. In the tutorials hands-on examples of stress analysis, limit load analysis etc. are demonstrated. In the computer assignments, example of stress analyses are handled based on the theoretical basis.
The CANVAS platform is used for formal interaction between you and the teachers. All the formal material and information about the course are placed in the CANVAS course homepage. Hence, there will be no other course-pm handed out. In CANVAS, announcements about special events in the course are made. Hence, you are advised to visit the CANVAS-page on a daily basis during the course. In CANVAS the reports for the computer assignments are handed in electronically with due consideration to the deadlines, cf. the detailed course-pm.
Digitals tools like Matlab and COMSOL are used in the course work. For the report writing, MS-office tools or equivalent softwares (e.g. Latex via overleaf) may be used.
Changes made since the last occasion
Due to the program-restructure, a new set-up of the course has been made 2021.
Before coming to the course you should have basic knowledge in:
- mechanics and strength of materials. Basic balance laws of Newton. Elasticity. Axial and bending action. Torsion. Yielding and failure.
- your skills in calculus, linear algebra and numerical methods will be further developed. (Multivariable analysis runs in parallel and will be developed).
- programming in Matlab. The course further develops your programming skills.
Formally, we expect you to have taken the courses: LMA401 Calculus, MVE580 Linear algebra and differential equations, LMT202 Mechanics, TME255 Strength of materials, LMA017 Mathematical analysis in several variables and LMU120 Applied FEM-analysis, or corresponding knowledge. Due to the restructuring, LMA017 runs in parallel and LMU120 is coming after in Q2.
After the completion of the course you should be able to:
- formulate the concepts of multiaxial stress and strain;
- determine the principal stresses and principal stress directions;
- formulate and analyze isotropic thermoelasticity;
- describe and analyze plane stress, plane strain and axisymmetry;
- formulate the concept of structural stability;
- solve simplified problems of structural stability;
- analyze stresses and deformations of 2D solids, plates and simplified shells;
- explain the stress distribution around concentrated loads;
- describe and analyze stress concentration factors.
