Liu, P. (author), Groves, R.M. (author), Benedictus, R. (author)Optical coherence elastography (OCE) has been applied to the study of microscopic deformation in biological tissue under compressive stress for more than a decade. In this paper, OCE has been extended for the first time, to the best of our knowledge, to deformation measurement in a glass fiber composite in the field of nondestructive testing. A...journal article 2014

Zadpoor, A.A. (author), Sinke, J. (author), Benedictus, R. (author)This article studies the properties of a wide range of friction-stir-welded joints with dissimilar aluminum alloys or thicknesses. Two aluminum alloys, namely, 2024-T3 and 7075-T6, are selected for the study and are welded in ten different combinations of alloys and thicknesses. The welding parameters are optimized for each configuration, and a...journal article 2010

Morinière, F.D. (author), Alderliesten, R.C. (author), Tooski, M.Y. (author), Benedictus, R. (author)An experimental study was performed on the repeated low-velocity impact behaviour of GLARE. Damage evolution in the material constituents was characterised with successive number of impacts. Records were correlated with visual inspection, ultrasound C-scan and chemical etching. The stiffness of the plate varied when cumulating the number of...journal article 2012

Pascoe, J.A. (author), Alderliesten, R.C. (author), Benedictus, R. (author)Current prediction methods for growth of disbonds under fatigue loading are generally based on a correlation with either the maximum strain energy release rate (SERR) or the SERR range. This paper highlights some issues with this approach. In particular, it is argued that the maximum SERR or the SERR range alone do not give sufficient...journal article 2014

Morinière, F.D. (author), Alderliesten, R.C. (author), Benedictus, R. (author)An analytical and experimental investigation into the low-velocity behaviour of GLARE Fibre-Metal Laminates (FMLs) has been performed. A quasi-static approach was developed to estimate the perforation energy absorbed between the constituents of GLARE. The analysis considered contact area increase during perforation and strain rate effect on...journal article 2012

Miesen, N. (author), Sinke, J. (author), Groves, R.M. (author), Benedictus, R. (author)The novelty of the research is the detection of different types of flaws in the prepreg carbon fibre-reinforced fibres (CFRP) layup compared to in cured products. This paper presents the development of a new method for in situ detection of prepreg CFRP production flaws combining laser displacement sensors and analytical modelling. Experimental...journal article 2015

Ghatak, K.P. (author), Bhattacharya, S. (author), Bhowmik, S. (author), Benedictus, R. (author), Choudhury, S. (author)We study thermoelectric power under strong magnetic field (TPM) in carbon nanotubes (CNTs) and quantum wires (QWs) of nonlinear optical, optoelectronic, and related materials. The corresponding results for QWs of III-V, ternary, and quaternary compounds form a special case of our generalized analysis. The TPM has also been investigated in QWs of...journal article 2008

Monaco, A. (author), Sinke, J. (author), Benedictus, R. (author)For aircraft structures, it is clear that the design and the selection of materials play an important role in the performance of the aircraft. The production costs are also important. The concept of tailor-made blanks (TMBs) is based on the use of dedicated blanks, made of different alloys and/or thickness in order to satisfy different demands...journal article 2008

Pascoe, J.A. (author), Alderliesten, R.C. (author), Benedictus, R. (author)The concept of relating fatigue disbond growth to the strain energy release rate (SERR) is critically examined. It is highlighted that the common practise of using only the maximum SERR or only the SERR range is insufficient to correctly characterize a load cycle. As crack growth requires energy, it is argued that growth should be related to the...journal article 2014
