WebStrain is the percent change in the length of the material. The stress-strain curve is the simplest way to describe the mechanical properties of the material. The stress-strain curve can provide information about a material’s strength, … WebFeb 9, 2024 · This is often achieved by tuning deformations through heterogeneous material stiffness or placing responsive materials at prescribed locations ( 20 – 22 ). For example, stiffness gradients or swelling regions can allow for expansion at different locations for prescribed, reversible shapes. WebThe stiffness of a component means how much it deflects under a given load. This depends on the Young's modulus of the material, but also on how it is loaded (tension, or bending) and the shape and size of the component. Specific stiffness is Young's modulus divided by density (but should more properly be called "specific modulus"). Design issues can engine oil burn
