This works proposes a novel approach to develop higher-order finite elements by taking progressive damage into account in the formulation. The is based on Carrera’s unified formulation (CUF) while model continuum mechanics (CDM) principles, which implemented as UEL (User Element subroutine) written FORTRAN and linked Abaqus. assessed simulating plate under distributed sinusoidal loads. Besides,...

The incorporation of higher order strain gradients into the constitutive equations of continuum damage mechanics is presented. Thereby, not only scalar-valued isotropic damage models but also anisotropic damage models allowing for directional dependent sti€ness degradation are elaborated. An elegant possibility of describing anisotropic material behavior based on the microplane theory is demons...

This paper presents an experimental investigation into the compression behavior of shape memory alloy hybrid composites (SMAHC) subjected to quasi-static loading taking into account of rotation effects of shape memory wire in basalt continuous filament (BCF) direct roving epoxy composite. Two types of specimen prepared, the BCF direct roving reinforced epoxy composite filled with shape memory w...

The use of composite structures in engineering applications has proliferated over the past few decades. This is mainly due to their distinct advantages of high structural performance, high corrosion resistance, high strength and weight ratio. They are however prone to fiber breakage, matrix cracking and delaminations which are often invisible. Although there are systems to detect such damage, t...

An analytical model is developed to study the ballistic behavior of multilayer composite armors subjected high-velocity impact projectiles with arbitrary angle incidence, shape, size, and frictional characteristics. The thickness compaction resulting from production process also accounted for, quantifying role curing pressure on enhancement toughness laminates. Finite element method simulations...

A finite element model was developed to investigate the influence of near surface orthogonal shear stress (OSS) on competitive failure mechanism between originated pitting (SOP) and subsurface spalling (SOS), which is intrinsic rolling contact fatigue (RCF). Surface roughness in heavily loaded non-conformal contacts causes competition SOS SOP. In this investigation, tribo-surface has been repre...

Concrete is a composite material with heterogeneities across multiple length scales. Degradation of concrete due to external loadings starts diffuse microcracking, followed by damage localization that eventually leads structural failure. Identification at an early stage degradation reduces the costs associated maintenance structure. Weak changes can be detected using ultrasonic waves (so-called...

Biosimulations employ Finite Element Method (FEM) to simulate complex biological systems in order to understand different aspects of human organs. The applications of FEM biosimulations range from human ear cochlear mechanics, cardiovascular, to neurovascular research. Performing these large Finite Element (FE) simulations, comparison and analysis of multiple simulation experiment results, and ...
