Strength of Materials I
The concept of mechanical stress – Single axis and plane stress conditions – stress analysis – MOHR cycles. – Strain gages – Deformation displacement relations, conventional conditions – Stress strain relations – HOOKE law – Applications in static definitive and static indefinite plane trusses. Thin-coated cylindrical pressure vessels. Thermal stresses. Energy and deformation work – energy theories – Principle of minimum energy deformation – Castigliano method – applications. Failure criteria.
Laboratory Exercises: Tensionaltesting, Impacttesting, Fatigue testing, Deformation Measurement, Hardness Testing.
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.
