The effect of clay on the mechanical properties of epoxy resins subjected to hygrothermal ageing [PDF]

open access: yesarXiv, 2016
Epoxy polymers are an important class of material for use in various applications. Due to their hydrophilic nature, epoxy resins tend to absorb moisture. Absorption of moisture degrades the functional, structural and mechanical properties. For polymers, it is known that moisture absorption can lead to both reversible and irreversible changes.

Improved calculation of the Young's modulus of rectangular prisms from their resonant frequency overtones by identifying appropriate shear constants [PDF]

open access: yesarXiv
Young's modulus is an important parameter for characterizing the strength of, and wave propagation through, a given material. This study improves the estimation of Young's modulus using the impulse excitation (IE) technique based on an experimental analysis of 19 borosilicate glass bars.
