In engineering materials terms the ratio of tensile stress (in mpa) to strain (in mm) within its elastic region is called the modulus of elasticity of the material (aka elastic modulus or youngs modulus). In the case of latex rubber, it has an elastic modulus of about 0. There are 4 such moduli youngs modulus axial modulus rigidity modulus bulk modulus the larger the value of the bulk modulus, the harder it is to compress the material. As strains are without any dimension, youngs modulus as same dimensions than stress thats to write effort by surface unity (for example n mm or mega pascal mpa). Elastomers do not escape to this rule and for low strains we can assimilate their behaviour to a linear one. youngs modulus (e) is defined as the ratio of the stress applied to the material along the. To determine the youngs modulus of the thin epicuticle, tensile tests were performed. To achieve this, stick insects were allowed to adhere onto a thin latex membrane, which was stretched while simultaneously observing the elongation of latex membrane and arolium contact area under a microscope. Where e youngs modulus g shear modulus p poissons ratio. 5 (assuming no volume change, the ratio of an isotropic material is exactly 0.). Youngs modulus of cnt-filled sr increased by 272 at 2 phr filler and reached as high as 706 at 8 phr filler, in contrast to the 125 increase for cb specimens at 10 phr. 81 prepared graphenesbr composites using a modified latex compounding approach, and a nearly 10-fold increase in the elastic modulus was attained upon. Modulus of elasticity - is a measure of stiffness of an elastic material. It is used to describe the elastic properties of objects like wires, rods or columns when they are stretched or compressed. Ratio of stress (force per unit area) along an axis to strain (ratio.). Youngs modulus (also referred to as the elastic modulus or tensile modulus), is a measure of mechanical properties of linear elastic solids like rods, wires and such. There are other numbers which give us a measure of elastic properties of a material, like bulk modulus and shear modulus, but the value of youngs modulus is most commonly used.
