## What is Design Stress?

Design stress is a term used in engineering and structural design to describe the maximum allowable stress that a material or structure can sustain under specific loading conditions, while still maintaining an acceptable level of safety and reliability. The design stress is typically calculated using various factors such as safety factors, load factors, and material properties. The design stress is typically compared to the material's yield strength, which is the stress at which permanent deformation or yielding occurs, to ensure that the material or structure does not fail due to excessive stress. The design stress is also compared to various codes and standards, such as building codes or industry-specific standards, to ensure that the design meets regulatory and safety requirements.
