Finite Element Analysis of A Strengthened Beam Deliberating Elastically Isotropic And Orthotropic Cfrp Material

Abstract

Using appropriate material properties for analyzing different models in academic and commercially availablefinite element software is one of the main concerns for design engineers and researchers. This paper demonstrates theimportance of using appropriate material properties for the models to be considered by engineers during finite elementmodelling. Two reinforced concrete (RC) beams strengthened with Carbon Fiber Reinforced Polymer (CFRP) strips areinvestigated, considering the CFRP elements as elastically isotropic and orthotropic materials. To show the significance ofthe selective material properties, all properties of the models are chosen to be exactly the same for the two beams except forthe CFRP strip. To validate the study, an RC beam is tested experimentally and the numerical results are compared to theexperimental test. The results show that CFRP with isotropic or orthotropic properties has no significant influence on beamresponses such as stresses, displacements and damage response under applied loadings.

Seismic Response Characteristics of RCC Dams Considering Fluid-Structure Interaction of Dam-Reservoir System

“…The linear assumption may not be fit to investigate RCC dams subjected to dynamic motions [35][36][37][38]. To date, many techniques such as smeared crack model, isotropic and anisotropic damage model have proposed to investigate the constitutive model of concrete materials and their complex mechanical reaction while subjected to ground excitations.…”

Simulating the Optimization of Carbon Fiber Reinforced Polymer as a Wrapping Structure on Piping System Using SolidWorks

“…As rapid development was done across decades, lately the mechanical properties of the CFRP were very much improved compared to other type of material especially materials like steel. In general, CFRP could have either isotropic or orthotropic properties subject to the fibers’ alignment [ 18 ]. Since there were not much mechanical properties differences in between the isotropic and orthotropic CFRP material, therefore this research takes the orthotropic properties into concern as lamination orientations plays the major role in this research and considering the accessibility of CFRP orthotropic property data that could give better analysis data based on axis [ 19 ].…”

The Effect of Material Stiffness on Dental Implant Stability – A Finite Element Analysis

“…Finite element analysis (FEA) is widely used computational method in dental implantology that allows investigators to predict the responses which are challenging to be determined in in vitro and in vivo works especially at the bone-implant interface [13][14][15]. FEA plays an important role in explaining mathematical modelling problems in many fields of science and industry such as through structural, fluid [16,17], thermal, fatigue, and fracture mechanics analyses [18][19][20][21][22].…”
