Cross-Sectional Analysis Of The Mechanical And Physical Properties Of Spruce Foundation Piles: An investigative analysis of moisture content, density, compressive strength, and modulus of elasticity across the cross-section of spruce foundation piles, with an emphasis on the predictive proficiency of micro-drilling methods

Summary<br/><br/>Numerous ancient historical constructions worldwide depend primarily on an extensive array of wooden foundation piles, as they are subject to loading conditions governed by the superstructure above. Wooden foundations transfer loads through a combination of compression and lateral resistance. The inherent strength of wood...

An Experimental and Numerical Study on Decayed Azobé Sheet piles

Given the desire to construct more structures using sustainable building materials, demand for wood and other bio-based building materials has risen dramatically over the decade. While timber itself is a carbon-neutral material and can sometimes even be carbon-negative, reusing wooden structural members made that have been in service for several...

Development of in silico models to guide the experimental characterisation of penile tissue and inform surgical treatment of erectile dysfunction

This paper presents a computational study to investigate the mechanical properties of human penile tissues. Different experimental testing regimes, namely indentation and plate-compression tests, are compared to establish the most suitable testing regime for establishing the mechanical properties of the different penile tissues. An idealised...

A structural and mechanical assessment of thrombus analogs formed under physiological pressure and flow

<b>BACKGROUND - </b>The success of the mechanical thrombectomy treatment in acute ischemic stroke is highly dependent on mechanical clot behavior and characteristics like stiffness. This mechanical treatment is tested in clot analogs. Realistic clot analogs could potentially be made in a realistic formation environment. The effects of blood...

Determination and analysis of the constitutive parameters of temperature-dependent dislocation-density-based crystal plasticity models

Physics-based crystal plasticity models rely on certain statistical assumptions about the collective behavior of dislocation populations on one slip system and their interactions with the dislocations on the other slip systems. One main advantage of using such physics-based constitutive dislocation models in crystal plasticity kinematic...

Non-linear block load corrections for dry docking

Damen is designing more and more slender hull forms, which leads to a small dock block contact area, and therefore a high load on the block bed. Dry docking is achieved by using multiple blocks located along the longitudinal length of the ship. Dock blocks are constituted by several layers, normally three or more. The configuration of the block...

Auxetic interval determination and experimental validation for a three-dimensional periodic framework

Auxetic behavior refers to lateral widening upon stretching or, in reverse, lateral shrinking upon compression. When an initially auxetic structure is actuated by compression or extension, it will not necessarily remain auxetic for larger deformations. In this paper, we investigate the auxetic range in the deformation of a periodic framework...

Breakage behavior of biomass pellets: An experimental and numerical study

The presence and generation of fines and dust in the bulk of biomass pellets have inflicted several problems in the supply chain during transportation and storage, and the breakage behavior of pellets has been scarcely studied so far. Fines and dust are the consequences of impact and abrasive forces through the whole supply chain; however, the...

The Structural Behaviour of Bundled Glass Columns: Finite Element Modelling and Experimental Validation

Researchers of TU Delft have been designing and engineering with columns created out of multiple glass rods that are bundled together to form a single column. These aesthetically attractive and slender columns were tested to ensure safety before implementation in the real structure: the Glass Truss Bridge located at the campus of the university....

Hybrid Timber Construction Technology: Investigation in a hybrid building construction technique, that could be encoded in a digital tool, by maximizing the use of local building materials such as natural timber, in seismic zone of Meghalaya, India

While the world is advancing with taller structures using engineered wood, little importance is being given to natural wood, which is abundantly available in most regions of the world. The lack of technological research using this material in its natural state has caused a drawback in its usage. Also, the dependence on engineered wood for modern...

Thin glass composite panel with 3D printed core: Thermal and structural properties

The research of this thesis is focussed on the thermal insulation and structural properties of a thin glass composite panel with 3D-printed polymeric core.<br/><br/>Aluminosilicate glass, used in this research, is only 0,5 mm thick. This aluminosilicate can be used to replace current windows and structural façade element to reduce the use of...

Response of Sandy Soil Stabilized by Polymer Additives

Traditional sandy soil stabilizers such as lime cement, fly ash and bituminous materials, etc., usually require long curing time. Hence now a day, polymer stabilizer is used more extensively because of its stable chemical property and shorter curing time. For the developing organization, it is important to judge the performance of stabilized...

Static and fatigue performance of thick laminates test design and experimental compression results

The behaviour of artificial archaeological remains during a one-dimensional compression test

The Dutch subsoil contains a lot of archaeological remains that need to be preserved for future generations. Until now, it is not possible to predict if these remains will stay intact under the pressure of a manmade structure like an embankment. The goal of this research is to investigate the behaviour of assemblies of artificial archaeological...

Static and fatigue performance ofthick laminates test design and experimental compression results

The aim of this work is to study the thickness effect in static and fatigue tests of glass-fibre unidirectional compression coupons. For this purpose, the self-heating effect, the effect of specimen geometry, and the influence of the manufacturing processes have been minimized. A scaled thickness compression coupon has been designed with the...

A damage tolerance study conducted with structure relevant specimens

A preliminary investigation is reported of the development of a Structure Relevant (SR-) specimen, which maintains the essential features of a stiffened panel configuration, in order to study damage growth behavior at limited cost. Several SR-specimens were fabricated, damage was applied, either through impacts or by the insertion of artificial...
