Effect of the stacking sequence on the impact response of carbon-glass/epoxy hybrid composites (2020)
Journal Article

This paper investigates low-velocity impact response of Quasi Isotropic (QI) hybrid carbon/glass fiber reinforced polymer composites with alternate stacking sequences. Cross-ply woven carbon and glass fibers were used as reinforcing materials to fabr... Read More about Effect of the stacking sequence on the impact response of carbon-glass/epoxy hybrid composites.

Three-dimensional strains on twisted and swept composite rotor blades in vacuum (2020)
Journal Article

This paper presents an investigation of the effects of tip sweep on highly twisted composite rotor blades by acquiring strain data in vacuum. Three parametric test cases were designed for strain measurements, and predictions from a special three-dime...

Nonlinear frequency domain solution method for aerodynamic and aeromechanical analysis of wind turbines (2020)
Journal Article

The aerodynamic simulations of wind turbines are typically carried out using a steady inflow condition. However, the aerodynamics and aeroelasticity of wind turbine blades can be significantly affected by inflow wakes due to the environmental conditi...

Direct numerical simulation of interaction between transient flow and blade structure in a modern low-pressure turbine (2020)
Journal Article

A feature of a modern aeronautical Low-Pressure Turbine (LPT) is the high blade loadings with complex, transient and separated flow regimes. Most existing research have focused only on analysing the transient flow and flow separation in such turbines...

Investigating the use of joint probability curves in coastal engineering practice (2020)
Journal Article

This paper investigates the inherent inaccuracy in the estimation of various extreme response variables (RVs) for different sea defence structures using joint exceedance curve approaches in common use around the UK. Utilising stochastically generated... Read More about Investigating the use of joint probability curves in coastal engineering practice.

Adaptive gain super twisting algorithm to control a knee exoskeleton disturbed by unknown bounds (2020)
Journal Article

Knee exoskeletons as wearable robots have been increasingly aimed to assist elderly and disabled people to increase their movement abilities through flexion/extension execution of the knee. In this paper, a robust controller was suggested for a new k... Read More about Adaptive gain super twisting algorithm to control a knee exoskeleton disturbed by unknown bounds.

DNS of secondary flows over oscillating low-pressure turbine using spectral/hp element method (2020)
Journal Article

This paper investigates the secondary vortex flows over an oscillating low-pressure turbine blade using a direct numerical simulation (DNS) method. The unsteady flow governing equations over the oscillating blade are discretized and solved using a sp...

Effect of graded compaction of tilled and untilled sandy loam soil on growth and yield of maize (2020)
Journal Article

The performance of maize on tilled and untilled sandy loam soil, under different levels of compaction of 0, 2, 4 and 6 tractor-wheel passes in a humid tropical environment was investigated with a Massey Ferguson (MF) 90-disc plough, mounted on an MF...

Application of a portable indentation rig with Rockwell indenter to determine mechanical properties and residual stresses on an aluminum plate (2020)
Journal Article

Measuring residual stresses is still a dilemma in many engineering applications. It is even more crucial when the industrial requirements demand for a non-destructive technique in order to avoid compromising the structural integrity of the engineerin...

Residual stresses measurement in hollow samples using contour method (2020)
Journal Article

Residual stresses are created usually undesirably during manufacturing processes, including casting, welding, metal forming, etc. Residual stresses alone or in combination with other factors can cause the destruction and fracture of components or sig...
