LEARNING OUTCOMES

The students attending this course gain the basic knowledge of the Strength of Materials necessary for the assessment of stresses, deformations and strength of uniaxial elements in uniaxial loading as well as in pressure vessels. Ability to solve static indefinite problems, ability to choose and use different failure and energy theorems. This knowledge is necessary and is used in many subsequent courses of Mechanical Engineering and Aeronautics, such as Strength of Materials II, Machine Design, Light Structures, Introduction to Composite Materials, Mechanical Behavior of Materials, Finite Elements for Structural Analysis, Mechanics of Composite Materials etc.

The learning outcomes of this course correspond to the descriptive indicator 7, according to the European Qualifications Framework.
