The class is composed by theory and tutoring. Tutoring is devoted in developing the ability of the students to easily present maccnine and demonstrate the behavior of the machine components. Based on macchie acquired knowledge at the end of the class, the students will be able to design machine components.

Furthermore, the student will improve their learning capability for future independent studies. Stress-strain behavior in elastic-plastic field o Incremental theory of deformation o Prandtl-Reuss equation o Equivalent stress-strain curve o Tresca plastic flow 2.

Low giovannozzo fatigue o Hardening and softening o Cyclic curve o Stress-number of cycle to failure curve o Strain-number of cycle to failure curve o Effect of mean stress o Effect of mean strain o Fatigue life estimation of machine components 3. Fatigue crack growth o Fatigue crack growth macchihe o Fatigue crack growth propagation law o Fatigue behavior of materials o Constant amplitude load fatigue life estimation o Variable amplitude load fatigue life estimation o Crack closure o Fatigue short-crack growth propagation o Microscopic phenomena 6.

Scheda Insegnamento

Power point presentation and traditional methods are employed during the class. Engineering problems, regarding the theoretical treated topics, will be analyzed during the tutoring.

Methods and Criteria for Learning Assessment. Students have to demonstrate their knowledge and capability in dealing with mechanical design of machine components. Student evaluation will be carried out by means of a written and oral exam.

Furthermore, students will be involved in a project where the design of a machine component is required. The final evaluation is based on the knowledge and the quality of exposition demonstrated during all the exams.
