In recent years, the scientific community has shown a growing interest in fiber-reinforced concrete (FRC) for modern structures due to its enhanced ductility compared traditional reinforced (RC). This paper introduces an analytical model that incorporates comprehensive fiber reinforcing index (RI) study various types of FRC. The analysis focuses on compressive and tensile behaviors, damage evol...

Fresh fruit micro-rupture generally occurs during mechanical handling, which severely affects the product’s postharvest quality along supply chain. An extended finite element (XFEM) model was developed for investigating fracture response of tomato under compression. A 1/4 modeled using three parts: exocarp, mesocarp and septa frame, pre-crack. amplitude curve-based uniformly distributed pressur...

We consider a standard sharp interface model for the fluid dynamics in a twophase incompressible flow, combined with a convection-diffusion model for solute transport. Some important numerical challenges related to these models are discussed. We present a finite element discretization method for the solute transport model. The method is based on an Eulerian approach, i.e. computational grids ar...

We consider a standard model for mass transport across an evolving interface. The solution has to satisfy a jump condition across an evolving interface. In the recent paper [C. Lehrenfeld, A. Reusken, SIAM J. Num. Anal., 51 (2013)] a new finite element discretization method for this mass transport problem is presented and analyzed. This method is based on a space-time approach in which a discon...

In the past decade, a combination of unfitted finite elements (or XFEM) with the Nitsche method has become a popular discretization method for elliptic interface problems. This development started with the introduction and analysis of this Nitsche-XFEM technique in the paper [A. Hansbo, P. Hansbo, Comput. Methods Appl. Mech. Engrg. 191 (2002)]. In general, the resulting linear systems have very...

Due to concerns over particle generation in conventional metal-on-polyethylene hip bearings used in total hip arthroplasty (THA), interest in advanced low-wear bearing alternatives such as ceramic-on-ceramic (CoC) couples has reemerged. While ceramics demonstrate excellent compressive strength, the brittle nature of the material reduces tensile strength, possibly leading to catastrophic fractur...

The elderly are more likely to suffer from fracture because of age-related trabecular bone loss. Different bone loss locations and patterns have different effects on bone mechanical properties. Extended finite element method (XFEM) can simulate fracture process and was suited to investigate the effects of bone loss on trabecular bone. Age-related bone loss is indicated by trabecular thinning an...

In this study, a multi-grid sampling multi-scale (MGSMS) method is proposed by coupling with finite element (FEM), extended (XFEM) and molecular dynamics (MD) methods. Crack studied comprehensively from microscopic initiations to macroscopic propagation MGSMS method. order establish the relationship between model, FEM used transmit displacement boundary conditions atomic model XFEM feedback cra...

Numerical simulations of cardiac blood pump systems are integral to the optimization device design, hydraulic performance and hemocompatibility. In wave membrane pumps, propulsion arises from propagation along an oscillating immersed membrane, which generates small pockets fluid that pushed towards outlet against adverse pressure gradient. We studied Fluid–Structure Interaction between flow via...

Accuracy and speed are two of the most important problems in the real-time Finite Element Method (FEM)-based simulations of surgical cutting [1][2]. While the latter can be gradually eased through GPU-based acceleration[3][4], the former hasn't been properly addressed even until recently. To enable realistic and accurate simulation, the cutting line should follow the exact movement of the user-...
