Materials and Strenghts of Materials (5cr)

Evaluation scale

0-5

Objective

Assessing the durability of structures requires knowledge of materials and mechanics. During the course you will learn about the mechanical properties of materials and the associated curves and fracture surfaces. You will also gain an understanding of statics and issues related to strength calculation.

Knowledge and understanding: you understand the basics of statics, materials and strengths.

Engineering practice: the ability to identify and understand the strengths of structures and outline mechanical calculation models and identify materials suitable for structures.

Content

Internal structure of materials, mechanical properties and the effect of internal structure on mechanical properties. Particle and rigid body statics. Stresses. Normal and shear stress. Normal stress in beam bending. Deflection. Fundamentals of torsion.

Teaching methods

Recorded lectures and calculation examples and face to face lectures. Assignments are based by problem-based learning. As help when you do your assignments you can use recorded lectures, examples, discussion list and files in your studying environment and also face to face lectures. You can do assignments individually or in groups, but you must always return the assignments individually. In distance learning you can join the webinars to get help in the assignments. In contact method you can get help for the assignments in the workshops. In the middle of the course, you give anonymous feedback.

Exam schedules

Two exams weeks scheduled in Moodle followed by the possibility of two re-exams in accordance with the degree regulations.

Student workload

Recorded lectures and examples or face to face lectures 28 h, learning assignments 28 h either online or by distance learning in study environment and independent learning work 79 h. Total 135 h learning work.
