Strength of Materials 2Laajuus (3 cr)

Objective

The students can calculate stresses affecting beam and plate structures and they are able to estimate their strengths. The students can calculate the effect of impact loads.

EA-KN EUR-ACE Engineering analysis: Students understand principles of strength of materials and how it is based on statics, mathematics and physics.

EA-EN Engineering practice: Students are able to use the principles of strength of materials to solve engineering problems.

TKNPE Basics of mechanical engineering: Students able to apply their knowledge of strength of materials to solve engineering problems with the help of statics, mathematics and physics.

Content

Hyperstatic beam- and framed structure. Obstructed torsion. Buckling . Lateral buckling. Bending of a curved beam. Plate and slab structures. Contact stresses. Impact loads.

Qualifications

The students have the basic knowledge of the strength of materials and they are able to static sizing of structures with the help of manuals and sizing table cases. The students can form a mechanic model from a structure under inspection and they can solve the stresses, tensions and deformations affecting it. The students can perceive the cases which require more precise and profound strength inspection.

Assessment criteria, satisfactory (1)
