SpletGood indicator for either the stiffness (high modulus) or the flexibility (low modulus) of a material. Impact Strength. Ability of a material to absorb shock and impact energy without breaking. Indicates toughness, helps you figure out if a part will survive when dropped on the ground or crashed into another object. Splet13. okt. 2024 · Young’s modulus is a property of a material that influences the deformation and elasticity of material in real-time. It can also be defined as the ratio of tensile stress to the tensile strain where the stress appears as the applied amount of force and measures the elasticity of a material (Wu et al. 2024). eurochange offices
