Effect of delamination on the stochastic natural frequencies of composite laminates

Probing the prediction of effective properties for composite materials

“…The functionally graded material (FGM) is a type of composite material which is inhomogeneous mixture of two materials (Kashtalyan, 2004;Woodward and Kashtalyan, 2011;Dey et al, 2015aDey et al, , 2015bDey et al, , 2019Mukhopadhyay et al, 2018Mukhopadhyay et al, , 2020Karsh et al, 2019;Dey et al, 2016). In recent studies, most of the researchers (Ansari et al, 2019;Wu et al, 2017;Zhang et al, 2020) fabricated and investigated these FGMs by reinforcing graphene and its derivatives into various types of matrices.…”

Caracterización dinámica vibratoria experimental de compuestos reforzados con fibra natural de fique

“…La resonancia mecánica es un fenómeno que se produce cuando un cuerpo por la acción de una fuerza externa vibra a la misma periodicidad que la frecuencia natural del mismo produciendo un aumento en la amplitud el cual puedes ser destructivo [29]. En el caso de los materiales compuestos producen efectos de delaminación como lo reporta Mukhopadhyaya et al [30], es por esta razón que es importante conocer los parámetros que puedan modificar las frecuencias naturales, como el aumento de cantidad de fibra natural, evitando de esta forma daños por vibración en aplicaciones de tipo industrial.…”

Behavior of Piles Reinforced by Geosynthetics Under Lateral Load

“…The use of fiber-reinforced polymer (FRP) bars and geosynthetic geogrids (G) as pile reinforcement materials was discovered to be a promising strategy, due to their high strengthweight ratio, durability, and high ability to anti-corrosion [7] [8]. Composite piles are commonly used as waterfront barriers, fenders, and bearing piles for light structures in ports due to the ongoing creation of novel composite materials [9][10][11][12][13]. They were also used in bridge rehabilitation work as load-bearing substructures [14].…”
