Damage process in composites subjected to low-velocity impact is investigated both experimentally and numerically. Drop-weight impact experiments are carried out, in which a model unidirectional [0/90]s carbon fiber reinforced polymer (CFRP) laminate beam is impacted by a cylindrical head creating an almost uniform two-dimensional loading condition. Damage sequence is visualized in real-time via ultra-high-speed camera and the resulting final failure patterns are characterized by a digital microscope. In the computational part, a three-dimensional finite element analysis is performed in ABAQUS/Explicit with the intraply matrix and delamination models. Damage initiation time, location and the interaction of failure modes are compared with the experimental data. A very good overall agreement between experimental and numerical results is observed.

Experimental and computational study of the damage process in CFRP composite beams under low-velocity impact Topac, O. Tanay; Gözlüklü, Burak; Gürses, Ercan; Çöker, Demirkan (2017-01-01) Damage process in composites subjected to low-velocity impact is investigated both experimentally and numerically. Drop-weight impact experiments are carried out, in which a model unidirectional [0(5)/90(3)](s) CFRP laminate beam is impacted by a cylindrical head creating an almost uniform two-dimensional loading condition. Initiation and progression of damage, consisting of matrix cracks and delamination, are visualized in real-time via ultra-high-speed camera at rates up to 60,000 fps and the sequence of ...
Excessive damage increase in dual phase steels under high strain rates and temperatures Cobanoglu, Merve; Ertan, Rasim K.; Şimşir, Caner; Efe, Mert (SAGE Publications, 2020-09-01) Damage formation in dual phase steels is a complex process and it may be sensitive to the deformation conditions and mechanisms. In this study, the damage parameter is measured and compared under quasi-static and industrial forming conditions (temperatures: 25 vs 200, 300 degrees C and strain rates: 10(-3)vs 10 s(-1)) for DP590 and DP800 steels. Resonance frequency and ultrasonic sound velocity techniques are utilized for the measurements to test the effectiveness and validity of each technique. At a given ...
Assessment and modelling of particle clustering in cast aluminum matrix composites Çetin, Arda; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2008) The damage and deformation behaviour of particle reinforced aluminum matrix composites can be highly sensitive to local variations in spatial distribution of reinforcement particles, which markedly depend on melt processing and solidification stages during production. The present study is aimed at understanding the mechanisms responsible for clustering of SiC particles in an Al-Si-Mg (A356) alloy composite during solidification process and establishing a model to predict the risk of cluster formation as a f...
Prediction of damage in R/C shear panels subjected to reversed cyclic loading Hindi, R; Mansour, M; Dicleli, Murat (Informa UK Limited, 2005-01-01) In this paper, the damage prediction of shear-dominated reinforced concrete (RC) elements subjected to reversed cyclic shear is presented using an existing damage model. The damage model is primarily based on the monotonic energy dissipating capacity of structural elements before and after the application of reversed cyclic loading. Therefore, it could be universally applicable to different types of structural members, including shear-dominated RC members. The applicability of the damage model to shear-domi...
Experimental investigation of nanofluids using terahertz time domain spectroscopy (THz TDS) Koral, Can; Okutucu Özyurt, Hanife Tuba; Altan, Hakan; Department of Micro and Nanotechnology (2012) In this study, suspensions of metallic nanoparticles in base fluids, nanofluids, are investigated by using terahertz time domain spectroscopy (THz-TDS). Nanofluids are used as the working fluid in a variety of applications especially for the purpose of heat transfer enhancement. Polar fluids are being used as the base in nanofluids for their tendency to stop aggregation and sedimentation. Polar fluids highly absorb THz signal. In order to select the best possible host, various polar liquids have been invest...
