Common Misconceptions on Rules of Mixtures

Please pardon me if I am preaching to the choir here. Rules of mixtures (ROM) are very simple mechanics models. Everybody on this site has a very good understanding of it. However, confusion and mistakes on ROM constantly appear in textbooks, journal articles, online learning materials, etc. See attached two wiki articles. The major confusing point is that vf*Ef+vm*Em is derived from the isostrain assumption and the upper bound. Both statements are incorrect. There might be two main reasons contributed to this mistake/confusion.

A brief review of modeling of composite structures

This paper provides a brief review on modeling of composite structures. Composite structures in this paper refer to any structure featuring anisotropy and heterogeneity, including but not limited to their traditional meaning of composite laminates made of unidirectional fiber-reinforced composites. Common methods used in modeling of composite structures, including the axiomatic method, the formal asymptotic method, and the variational asymptotic method, are illustrated in deriving the classical lamination theory for the composite laminated plates to see their commonalities and differences.

iVABS

Dear All,

I am excited to share that we recently developed iVABS as an integrated VABS-based framework for design and optimization, parametric studies, uncertainty quantifications of composite rotor blades, and other beam-like structures. This tool is particularly useful for rapid design of composite slender structures with accuracy of detailed 3D FEA at the speed of simple engineering beam theories.
