WebJun 17, 2024 · When an object is being squeezed from all sides, like a submarine in the depths of an ocean, we call this kind of stress a bulk stress (or volume stress ). In other situations, the acting forces may be neither tensile nor compressive, and still produce a noticeable deformation. WebDec 22, 2024 · Young’s modulus Y is the elastic modulus when deformation is caused by either tensile or compressive stress, and is defined by Equation 7.6.4. Dividing this equation by tensile strain, we obtain the expression for Young’s modulus: Y = tensile stress tensile strain = F ⊥ A ΔL L0 = F ⊥ A = L0 ΔL. california bird nerds coupon
