Material joint interface

A material joint interface is the boundary where two different materials are connected or meet, like the seam between two pieces of metal or plastic. It’s a crucial area where forces and stresses transfer from one material to another. The properties of this interface—such as how well the materials bond and how they respond to loads—affect the overall strength, durability, and performance of the assembled structure. Proper design and treatment of the joint interface ensure the materials work together effectively and avoid issues like cracking, loosening, or failure over time.
