Master's Thesis from the year 1997 in the subject Engineering - Mechanical Engineering, grade: -, - (u.o.technology), language: English, abstract: A study of metal cumulative fatigue damage at multilevel stress programs using 2024- T 4 AI -Alloy is carried out in this investigation. Specimens are designed and fabricated. The tests are performed under multiaxial fatigue in phase combined loading bending and torsion, with zero mean stress (R=-l) at room temperature. Five groups of multiaxial fatigue experiments are performed, constant amplitude, linear increasing and decreasing, Low-High...
