What defines a kink in a structural material?

A kink in a structural material is defined as a sharp bend of more than 90 degrees. This characteristic is significant because kinks indicate a localized deformation where the material has experienced excessive stress or strain. When a structural element bends sharply, it may compromise the integrity of the material, leading to potential failure. The formation of a kink often results from factors such as overloading, improper handling, or manufacturing defects.

Understanding what constitutes a kink helps engineers and technicians assess the health of structural components and make informed decisions regarding repair or replacement. The presence of a kink can signal the need for a thorough inspection to determine whether the structural member can continue to perform its intended function safely.
