Structural Mechanics and Strength of Materials

Aim

The aim of the course is to give the students knowledge within structural mechanics and strength of materials as a basis for abilities within structural design. For areas included in the course, the students should be able to:

• Use proper terminology; Use proper denotations; Describe sectional entities and types of stress;
• Define used concepts, like normal and shearing force, bending and torsion moment, stress, strain, elongation, deflection; Describe various elements of structure and types of structures;
• Explain the function of structures; Calculate external and sectional entities as well as deflections for standard cases; Calculate external and sectional entities as well as deflections for combinations of standard cases; calculate stresses for typical loads and simple elements of structure; By exceeding determinations judge the correctness of calculations done; Carry through and report on a structural design assignment according to conventions; Use a computer program for the calculation of structural mechanics;
• A structure given, suggest a proper model of calculation considering loads as well as design; Calculate external and sectional entities as well as deflections for other than standard cases; By proper approximations or otherwise judge the reasonableness of calculations done ; Calculate stresses for combined loads and non standard structural elements; Optimize a structure for a given load;
