Mechanics and mechanisms of fracture processes and their engineering theoretical treatment
Objective
Understanding of fracture mechanisms of engineering materials and structures. Theoretical foundation of engineering fracture mechanics and their basic models. Knowledge how to deal practically with problmes of cracks and fracture
Content
Theoretical foundation of engineering fracture mechanics, including stability criteria of cracks in elastic and elastic plastic materials, definition and calculation of stress intensity factors, J-Integral, crack-tip opening displacement. Practical application of fracture mechanics: Calculation of crack tip loading in structural parts, safety analysis, safe life prediction for sub-critical crack growth, theoretical treatment of hot-spots and sharp notches.
