Defects in Crystalline Solids (Part-I)

Delve deep into the defects of material and gain extensive knowledge about dislocations in various crystals.

IIT Kanpur and NPTEL

About the Course

The Defects in Crystalline Solids (Part-I) course will teach students the intricacies of defects in certain materials. Students will also learn about the role of defects in determining the properties of materials as a whole. They will gain thorough knowledge about several dislocations in the structure of various crystals and their elastic fields. Additionally, they will get an overview of the mechanisms of plastic deformation and understand the role of dislocations in plasticity, fracture, fatigue, and creep. Prof. Shashank Shekhar, an assistant professor at IIT Kanpur, will be in charge of teaching this part of the course.
