Using the Modulus of Elasticity Formula The modulus of elasticity equation is used only under conditions of elastic deformation from compression or tension. The modulus of elasticity is simply stress divided by strain: E=σϵ with units of pascals (Pa), newtons per square meter (N/m2) or ne...
we take the strain (no units) on the \(x\)-axis and stress (\(\rm{Pa}\) or \(\rm{MPa}\)) on the \(y\)-axis. The slope of the graph under elastic limit gives Young’s Modulus of Elasticity
The usual formula for the elastic modulus E of a crosslinked highly elastic network E = 3 ρRT/Mc involves molecular weight between crosslinks Mc. It has to be modified by several factors such as the fraction not involved in any external stress and the initial molecular weight distribution. ...

Figure 2: Temperature dependency of Young’s modulus and CTE with Tg=142°C To better understand the temperature-dependent structural properties, an example was simulated with an existing analytical solution to verify the solver. A rectangle bar was placed along the z-axis and boundary const...
5 a, shown is micropost arrays with height of 10 μm and diameter of 2 μm and elastic modulus of 2.41 MPa). Cell–cell adhesion forces were derived by the zero-sum force balance between the two cells (Fig. 5 b). Measurement results from the micropost arrays show that DPNTP ...
Liu et al. [53] proposed a new model to calculate the hardness of a solid material, which is, Hv = 0.92 K1.137G0.708,K=Sheremodulus(G)Bulkmodulus(B) According to the formula the calculated hardness of our studied compounds are listed in Table 3 with similar type of Pt-based ...
The two fiber designs display almost identical elastomeric features with fracture strain reaching up to 599 ± 73% and 557 ± 54%, and Young’s modulus as low as 3.4 ± 0.6 MPa and 3.8 ± 0.3 MPa, respectively. A photograph showing a triboelectric fiber under ...
