Summary: The study evaluated the effective elastic properties of unidirectional banana fiber-reinforced polystyrene composites through numerical homogenization approach, and found that properties such as longitudinal modulus, transverse modulus, in-plane Poisson ratio, and in-plane shear modulus were affected by parameters like fiber volume fraction and cross section. The predicted numerical results obtained via finite element analysis were in good agreement with existing phenomenological analytical model predictions.

Summary: This research investigates the progressive failure mechanisms and variation in the mechanical behavior of dissimilar materials hybrid joints at elevated temperatures. Experimental analysis reveals distinct failure mechanisms in the worksheets, while computational analysis validates the findings. The study also examines the progressive damage in the CFRP sheet and evaluates the degradation in mechanical behavior at high temperatures. The research contributes to understanding the behavior of hybrid joints under high temperature conditions and can be applied to other dissimilar materials configurations as well.

Summary: A scalable manufacturing method for producing biocompatible few-layered graphene nanosheets was developed using hydrodynamic cavitation and serum albumin. By studying the effects of exfoliation time, it was found that as the time increased, the number of graphene layers decreased while disorder increased. Analysis and simulation models were designed to potentially improve graphene synthesis and quality based on cavitation numbers calculated through ANSYS simulation.
