Course Objective During computation of a design problem or manufacturing processes, it is essential to have knowledge on the mechanical behavior of the selected/utilized material. In this course the aim is the provide a general knowledge on the process, structure, mechanical property and performance correlation of materials, the factors which affect the mechanical behavior of materials and strengthening mechanisms for metals. Furthermore, it is also aimed to provide some general knowledge on material behavior at nano and micro-scale due to their increased importance in engineering applications. The ultimate goal of this course is to increase the confidence of students in utilizing materials in their computational studies in which they participate in this division and in their future studies.
Course Content Strain and stress relationships, elastic and inelastic deformation of materials, crystalline structure and defects, slip in crystals, properties and mechanics of dislocations, strengthening mechanisms, failure mechanisms, material behavior at micro and nano scale.
