Ulyanov, Boris (author)Liquid crystalline polymers have recently attracted attention for their great tensile properties. However, their interlaminar fracture toughness is low. To solve this, toughening approaches inspired by Nature are applied, exploiting the shaping freedom of fused deposition modelling. Three approaches are studied: the matchstick approach, z...master thesis 2023

Pouchias, Konstantinos (author)Lugs are a specific type of joint with a semi-circular geometry around the pinhole utilized in the aerospace field. Its distinct geometry and ability to carry loads in its plane make it a very common choice for design engineers. Although this type of joint is widely used, there are no analytical equations that can predict the stresses around the...master thesis 2023

Shi, Z. (author), Su, Q. (author), Kavoura, Dr. Florentia (author), Veljkovic, M. (author)To establish the tensile constitutive model of ultra-high performance concrete containing coarse aggregate (CA-UHPC), monotonic and cyclic uniaxial tensile tests for CA-UHPC with fiber volume fractions of 2.5% and 2.0% were conducted. Test results showed that CA-UHPC exhibits approximately linear stress-strain relation up to the tensile strength...journal article 2023

Paknahad, A. (author), Goudarzi, M. (author), Kucko, Nathan W. (author), Leeuwenburgh, Sander C.G. (author), Sluys, Lambertus J. (author)Calcium phosphate cements (CPCs) have been widely used during the past decades as biocompatible bone substitution in maxillofacial, oral and orthopedic surgery. CPCs are injectable and are chemically resemblant to the mineral phase of native bone. Nevertheless, their low fracture toughness and high brittleness reduce their clinical...journal article 2021

Arano, Assis (author), Colombo, Matteo (author), Martinelli, Paolo (author), Øverli, Jan Arve (author), Hendriks, M.A.N. (author), Kanstad, Terje (author), Di Prisco, Marco (author)Advanced numerical modeling of high-strength concrete (fc>60 MPa) structures designed to withstand severe thermal conditions requires detailed and reliable information on the mechanical properties of the material exposed to elevated temperatures. The only uniaxial compressive strength variation with temperature is not enough to satisfy the...journal article 2021

Kotteman, Geerte (author)Additive manufacturing (AM), or 3D printing, is emerging as a technology for different applications made of steel. It is expected that in the coming years the construction industry will benefit from the free and lightweight forms that can be fabricated and the possible material savings. A few experimental results of 3D printed stainless steel...master thesis 2020

Versluis, Barry (author)Many laboratory tests of samples where the rock fractures are based on<br/>meso-scale (cm) characterization of effective ‘intact’ strength parameters neglecting the microstructure effects. Understanding fracturing processes at<br/>micro-scale (mm) will require models with microstructure data. However,<br/>data is lacking on micro-scale.<br/...bachelor thesis 2020

Ren, D. (author), Houben, L.J.M. (author)Unlike the notched specimens for conventional concrete fracture tests, this paper introduces a deformation-controlled uniaxial tensile test on an un-notched specimen. The surface of the dog bone-shaped specimen is a second order parabolic curve, and the gradual change in the specimen shape does not lead to extreme stress concentrations....journal article 2020

Jing, R. (author), Varveri, Aikaterini (author), Liu, X. (author), Scarpas, Athanasios (author), Erkens, S. (author)Accelerated pavement testing (APT) is an effective method in evaluating pavement performance by applying wheel loading and speed under controlled conditions. This study aims to investigate the effects of wheel loading, speed and ambient temperature on the pavement responses at different directions and depths of pavement structure. A two-layer...book chapter 2020

Paknahad, A. (author), Kucko, Nathan W. (author), Leeuwenburgh, Sander C.G. (author), Sluys, Lambertus J. (author)Since their discovery in the 1980s, injectable self-setting calcium phosphate cements (CPCs) are frequently used in orthopedic, oral and maxillofacial surgery due to their chemical resemblance to the mineral phase of native bone. However, these cements are very brittle, which complicates their application in load-bearing anatomical sites....journal article 2020

van Veen, Dennis (author)Additive manufacturing (AM) is currently making a transition from mainly being used for prototyping to an alternative for conventional production methods. AM provides more freedom in design geometry combined with the possibility to produce (complex) products in low quantities. As a result, the need arises for printed parts with consistent...master thesis 2019
