Research Internship under Dr. Raghu Ram Karthik Desu, Assistant Professor at Mechanical Engineering Department, NIT Trichy. The work involved computing the forces exerted by granules (particles) arranged in hexagonal packing in 2D; on the walls of the container and how it varies with the number of layers,
number of particles in each layer and how force concentration takes place because of defects. All this was done using Discrete Element Method.
