Subject syllabus:

1. Test methods for evaluating the material properties and their distribution. 2. Determination of mechanical characteristics by tensile test – yield strength, Young´s modulus, tensile strength, elongation, contraction, strain hardening exponent. Overview of hardness test methods, principles. 3.-4. Fundamentals of fracture mechanics – methods of loading of the body with a crack. Linear elastic fracture mechanics (stress in a cracked body, driving force of crack, fracture toughness), elastic-plastic fracture mechanics (crack tip opening displacement, J-integral, stable crack growth under uniaxial loading). 5. Test methods for determining the fatigue characteristics of materials (S-N curve, Manson-Coffin curve). Evaluation of the resistance of the material to fatigue crack growth. 6.-7. Evaluation of the fracture behavior of metallic materials. Philosophy of transition temperature – Charpy impact test, Drop-weight test (DWT), Drop-weight tear test (DWTT), Impact bend test for large bodies (DT-dynamic tear). Philosophy based on fracture mechanics – the general temperature dependence of fracture toughness, plane-strain fracture toughness KIC, determination of fracture toughness in the transition region, determination of fracture toughness using multi-specimen testing, determination of the reference temperature T0. 8.-9. Procedures for determining the creep characteristics of metallic materials. Limit temperature Tg, creep curve. Basic characteristics of the creep resistance of materials. Practical examples of the evaluation of creep test results. 10.-11. Evaluation of resistance of structural steels to stress corrosion cracking and corrosion fatigue in aqueous environments. Mechanism of stable crack growth. Evaluation of resistance of steels to hydrogen embrittlement. 12. Evaluation of mechanical properties of structural steels using penetration tests. Principle of a ball penetration test (Bulge Punch Test). Procedure for performing time-independent penetration tests. Determination of the yield strength and tensile strength of steel from the results of penetration tests. 13. Determination of the transition behavior of steel and creep characteristics from the results of penetration tests. 14. Estimation of the fracture toughness from the results of penetration tests. The two-stage method to determine KIC. Direct estimation of the fracture toughness from the results of penetration tests. Innovative approach to the estimate of the fracture toughness JIC.
