Purpose of class
The aim of this course is to understand the elastic-plastic properties of (metal) materials, to develop the concepts of material mechanics, mechanical design and drafting, and to understand the design and processing methods of structures and component elements under complex stress.
Course description
In ”Steel Manufacturing Processes”, the elastic-plastic behavior and fracture of steel (metal) materials, which are widely used in the manufacture of structures and component elements, are explained. In addition, design and fabrication methods for structures and component elements made of steel (metal) materials under combined conditions by tensile and shear stress, and fatigue loading conditions are explained. The topics of ”joints and keys” may be added depending on the progress of the lecture.
Each class consists of a lecture and exercises, and the achievement of the objectives will be evaluated by examinations based on the exercises.
Goals and objectives
  1. To understand the fundamental elastic-plastic properties of steel (metal) materials.
  2. To apply the basic concepts of material strength and mechanical design and drafting to design problems involving steel (metal) materials.
  3. To understand design methods and machining of mechanical components under combined stress and fatigue loading conditions.
