Stiffness

Definition

Stiffness is the quality of resistance to deformation on the part of a material, a component member of a structure, or the whole structure.

Purpose

The purpose of stiffness is to ensure that materials and structures can withstand applied forces without excessive deformation, maintaining their shape and functionality.

Examples of Use

• Structural beams are designed with sufficient stiffness to support loads without bending.
• Engineered wood products, like laminated veneer lumber, offer increased stiffness for use in construction.
• Automotive components are made with materials that provide stiffness to maintain structural integrity during use.

Related Terms

• Elasticity: The ability of a material to return to its original shape after deformation.
• Rigidity: The inability of a material to be easily bent or flexed.
• Flexural Strength: The ability of a material to resist deformation under load.

Notes

Stiffness is a critical property in engineering and construction, ensuring that structures and components perform reliably under various loading conditions.
