Abstract:
Purpose The purpose of this paper is to evaluate the efficiency of the fast multipole boundary element method (FMBEM) in the analysis of stress and effective properties of 3D linear elastic structures with cavities. In particular, a comparison between the FMBEM and the finite element method (FEM) is performed in terms of accuracy, model size and computation time. Design/methodology/approach The developed FMBEM uses eight-node Serendipity boundary elements with numerical integration based on the adaptive subdivision of elements.

We analyse the use of linear data structures that are designed specially for GPU processing. We present the examples of calculations for the standard first order FEM approximation and typical contemporary hardware. We draw the conclusions on the feasibility of the proposed approach

This study applies the Finite Element Method (FEM) to analyse the structural behaviour of a cantilever beam subjected to a distributed load. Using aluminium as the beam material (E = 70 GPa, ν = 0.33), a 3D CAD model was developed in SolidWorks and meshed with tetrahedral elements in ANSYS. The analysis involved defining appropriate boundary conditions, where one end was fully fixed, and a uniform force of 500 N/m was applied at the free end. A linear static analysis was performed to evaluate stress distribution, displacement, and strain energy density. Results indicate that stress concentrati

The design codes and calculation methods related to the corrugated steel plate (CSP) bridges and culverts say only on the minimum soil height. This value is connected with the bridge span and shell height. In the case of static and dynamic loads (like passing the vehicles), such approach seems to be reasonable. However, it is important to know how the CSP bridges with high the soil covers behave under the seismic loads.

Structural assessment is a main concern when designing and operating any sort of offshore structure. This assessment is meant to ensure that the structural integrity is preserved along the lifespan of the asset, withstanding the worst sea-states that will be encountered and making sure that the accumulated fatigue damage will not jeopardize its structural integrity neither. The purpose of this paper is to present a fast and reliable hydroelastic model.

Abstract:
Bolted connections are widely adopted in steel structures and their behaviour affects to a large extent the global response of the system. High-strength bolts of type HV are commonly employed. Under pure tension, these bolt assemblies usually fail by thread stripping. However, it was observed experimentally that, under combined tension and bending, the failure mode changes to fracture of the shank. The former loading condition commonly occurs in the case of thick extended end plate connections and the latter in the case of flush end plates. In order to analyse the behaviour of the structure, t

It accommodates general, conforming space discretizations and naturally accommodates discretization of infinite horizon evolution problems.

Abstract:
Abstract In order to monitor in-time the occurrence of localized corrosion in concrete structures (viaduct, aqueduct, PCCP, pre-stressed and post-tensioned structures), a multi-reference electrode was proposed and studied, consisting of a series of continuous metallic wires able to measure the potential of carbon steel rebars and tendons. Because chloride-induced pitting may provoke hydrogen embrittlement of high strength steel, an early detection of corrosion initiation is very important to avoid such brittle fracture. Laboratory tests on mortar samples simulating post-tensioned tendons corro

Abstract:
The paper presents an overview of the smoothed finite element methods (S-FEM) which are formulated by combining the existing standard FEM with the strain smoothing techniques used in the meshfree methods. The S-FEM family includes five models: CS-FEM, NS-FEM, ES-FEM, FS-FEM and α-FEM (a combination of NS-FEM and FEM). It was originally formulated for problems of linear elastic solid mechanics and found to have five major properties: (1) S-FEM models are always “softer” than the standard FEM, offering possibilities to overcome the so-called overly-stiff phenomenon encountered in the standard th

Abstract:
Gas turbine combustor design process has significant number of design parameters because of contained complex phenomena. One of the most complicated of these is the heat transfer process of combustor liners. Heat transfer studies are performed in preliminary design phase by the help of one-dimensional tools and combustor geometry is shaped to satisfy design requirements. However; in the detail design phase, a fine tuning can be required to optimize it by using 3D CFD analysis. Conjugate heat transfer is a powerful tool to simulate interaction between reacting flow and combustor liners in detai

Fused Deposition Modeling (FDM - a technology of additive manufacturing) parts entail a certain amount of ambiguity in terms of its material properties and microstructure due to its manufacturing technique. Therefore, an FDM part differs from its design model in terms of strength and stiffness. With an increasing amount of FDM parts being used as end use products, it is necessary to simulate and analyze them. Due to the differences in microstructure and material properties of FDM parts, it is necessary to determine the accuracy of analysis methods like Finite Element Analysis (FEA) while analy

Abstract:
Developing a numerical and algorithmic tool which correctly identifies unyielded region in the yield stress fluid flow is a challenging task. Two approaches are commonly used to handle the singular behaviour at the yield surface, i.e. Augmented Lagrangian approach and the regularization approach, respectively. Generally in the regularization approach, solvers do not perform efficiently when the regularization parameter gets very small. In this work, we use a formulation introducing a new auxiliary stress [1]. The three field formulation of yield stress fluid corresponds to a regularization-fre

Abstract:
Reviews the available sensors for monitoring hazardous ground movement. Our review was limited to airborne and spaceborne sensors for access, performance, and productivity considerations. It was observed that certain ground movement is comparatively localized, e.g., earthquake faulting, while other activity may extend for thousands of kilometers, e.g., frost heave. Accordingly, we have considered two operating modes for the sensor-platform system, namely, site-by-site and continuous corridor.

Abstract:
The current calculation methods for determining the tooth root load capacity of polymer gears (e.g., VDI 2736) are based on the same assumptions as those for steel gears. However, due to the non-linear material behavior, temperature, and rate dependency of polymers, these predictions are often inaccurate. A previous study employed rate-dependent nonlinear viscoplastic finite element (FE) modelling of polyoxymethylene (POM) to quantify material influences not considered in standard metal gear assumptions.

ABSTRACT Postharvest losses of fresh produce are estimated globally to be around 30%. Reducing these losses is considered a major solution to ensure global food security. Storage at low temperatures is an efficient practice to prolong postharvest performance of crops with minimal negative impact on produce quality or human health and the environment. However, many fresh produce commodities are susceptible to chilling temperatures, and the application of cold storage is limited as it would cause physiological chilling injury (CI) leading to reduced produce quality.

Abstract:
Fatigue failure is a time-delayed failure that is one of the major threats to the pipeline integrity. For crack-like gouges in dents, the crack grows due to pressure cycling and eventually fails by fatigue. This work, which was funded by PRCI via Project MD-4-16, developed a viable engineering approach and a pragmatic fatigue model for predicting fatigue life of dents and gouges in pipelines. In particular, an equivalent stress method was developed with use of finite element analysis (FEA), and the crack driving force was determined based on the FEA results and the stress intensity factors (SI
