Structured Approach In Teaching Intermediate Mechanics Of Materials

Analyzing photovoltaic module mechanics using composite plate theories and finite element solutions

“…As visible in Figure 8, all models correctly predict compressive stress at the top glass surface, which becomes tensile by the bottom backsheet surface. Plate theory predictions are exactly linear and symmetric and are defined for the full thickness dimension, with the neutral plane occurring at the geometric center as expected from equation (15). Results are modulus independent since flexural rigidity dropped from equation (15) due to linearity between stress, strain, and deflection.…”

Results are modulus independent since flexural rigidity dropped from equation (15) due to linearity between stress, strain, and deflection. Homogenized finite element models are also largely modulus-independent and linear but show some discretization effects in the region formerly assigned as the module backsheet.…”

“…Rule of mixtures: Series configuration. For a composite loaded in the opposite orientation as reinforcing fibers, where fiber and matrix must each carry load sequentially in series, the expression for Youngs modulus is 15 :…”

Encapsulation of Hydrogen Molecules in C50 Fullerene: An ab Initio Study of Structural, Energetic, and Electronic Properties of H2@C50 and 2H2@C50 Complexes

“…An exciting approach to understand the mechanism of host–guest interactions in H 2 @C 50 and 2H 2 @C 50 is to calculate their SEs. By definition, the energy stored in a body because of deformation is called the SE . The SEs stored in n H 2 @C 50 ( n = 1 and 2) systems are determined by the overall summation of the SE of the host (C 50 ) and that of the guest ( n H 2 ), as shown in eq …”

Mom In Action

“…By connecting concepts to their historical evolution and their usage in advanced topics one builds a story of a concept which is important for motivation as well as for retention of the concepts as described in Section 3. Ideas discussed in this paragraph have been elaborated by Vable for the introductory mechanics of materials course 5,6 and for intermediate mechanics of materials course 7,8 .…”
