Eligibility Criteria
Certification Qualifying Details
The candidates must pass the written examination by registering for the exam on the NPTEL official website to get a certificate.
What you will learn
The students will learn from the fundamentals to advanced concepts of point, space groups symmetry, vector and tensor applications in crystallography. After completing the Crystals, Symmetry and Tensors certification syllabus, they will gain a deep understanding of the definition, properties of mathematical groups, stereographic projection and matrix representation of symmetry operations.
Upon completion of the Crystals, Symmetry and Tensors training, the students will be able to calculate the useful elastic properties such as modulus, Poisson ratio and others using tensor methods. With the leading industry experts support students will gain hands-on experience to apply the learned concepts and methods in real-world projects.
