Class Objectives
/Class Outline Aim
Ability to identify the fatigue damage mechanism with the aid of the Fractography.
Ability to perform fatigue design to ensure long-term reliability of the machine and structure.
Ability to perform, such as fracture mechanics analysis and material selection for the brittle fracture prevention.
Acquisition of basic knowledge to perform the destruction management design of large structures.
Summary
As well as lectured fatigue strength of various mechanical material consisting of the various structures, description of the fatigue design standards such as nuclear devices will be is performed and described fatigue design approach. Subsequently, will be described fracture management control design brittle fracture prevention was mainly with fracture mechanics. In particular, consult damage analysis example and fracture cases of large welded structures brittle fracture becomes a problem. Finally, Factory tours of the actual design and manufacturing will be held.
