the rule of mixture is the simplest way to calculate the properties of mixtures only taking account the fraction and a parameter here elastic modulus of each component. it is written : e composite =v particle *e particle v polymer *e polymer v and e are the volume fraction and elastic modulus of each component.
the elastisitymodulus or e-modulus is a property of a material like concrete or steel whichs tells how much tension is needed to make it a little bit longer or shorter when you pull at 2 ends of a steal beam itll be a bit longer then when you press it together .

mechanical properties: wood lumber versus plastic lumber and thermoplastic composites this study compares the modulus of elasticity and the flexural, compressive, tensile and shear strengths
in materials science, a general rule of mixtures is a weighted mean used to predict various properties of a composite material made up of continuous and unidirectional fibers. it provides a theoretical upper- and lower-bound on properties such as the elastic modulus, mass density, ultimate tensile strength, thermal conductivity, and electrical conductivity. in general there are two models, one for axial loading, and one for transverse loading. in general, for some material property e \displayst
modulus of elasticity flexural modulus the highest values of the modulus of elasticity among the thermoplastic products were found in pp-, hdpe- and pvc-based composites, and all are in the same region, between 5000 mpa and 9000 mpa, as the wood species' lowest values . when analysing only the commercialized thermoplastic products, the highest flexural modulus is close to 6000 mpa, close to the five lowest wood species' flexural modulus among the 195 species analysed for this property.

duralife outperforms the competition. a deck boards modulus of elasticity moe and modulus of rupture mor are good indicators of its ultimate performance and resistance to flex or sagging between joists. the higher the value, the better its performance. *data reflects actual duralife siesta decking test results and an aggregate of other manufacturers published data.
average of the full composite inertia and the inertia obtained from cracked section theory. if the neutral axis falls within the deck, only the concrete above the deck is considered. the criteria states that shrinkage reinforcement shall be pro vided equal to 0.001 of the area of concrete above the steel deck.

seven trust is as good or better for decking than all other woods, except seven trust. seven trust is more durable, lasts longer, is heavier, stronger, has more modulus of elasticity, more modulus of rupture, and is plain old harder. really when it comes to decking characteristics seven trust does not beat seven trust in any category.
ec s is the modulus of elasticity for strength design. for lrfd, e c s is taken directly as the modulus of elasticity of the material assigned to the composite section. for asd, e c s is calculated as 33 * gamma c1.5 * f ' c ksi , where gamma c is the weight per unit volume
