Material, acoustic, and mechanical properties of mosquito and midge antennae
… end, Confocal Laser Scanning Microscopy (CLSM), Finite Element Modelling (FEM) and Laser Doppler Vibrometry (LDV) were employed. The combination of the first two allows, in absence of prior knowledge of the material properties of mosquito or midge antennae, to assess the material structure and to …

Optimised solder interconnections in crystalline silicon (c-Si) photovoltaic modules for improved performance in elevated temperature climate
… investigated utilising a combination of ANSYS finite element modelling (FEM), Taguchi L25 orthogonal array and analytical techniques. The investigated RIFs are operating temperature, material combination and interconnection geometry. Garofalo creep relations and temperature dependent Young’s …

Electrocaloric materials and devices
… | ∼ 3.5 K near 180 K with |∆E| = 780 kV cm−1. Finite element modelling (FEM) was used to optimise the geometry of multilayered capacitors (MLCs) for EC cooling. Intrinsic cooling powers of 25.9 kW kg−1 are predicted for an optimised MLC based on PVDF-TrFE with Ag electrodes.

Thermomechanical Stress in Solar Cells and Modules: A Finite Element Modelling and Experimental Investigation
… stress in Si cells and modules by utilising finite element modelling (FEM) complemented by experimental validations. Models were developed to analyse the stress evolution in Multi-Busbar (MBB) tiled modules after soldering and lamination. The impact of cell overlapping in modules and the …

Circular Reinforced Concrete Columns Damaged By Fire and Retrofitted With Cfrp and Steel Jacketing
… concrete structures rarely collapse within a finite fire duration and can be successfully repaired. Along with the increasing number of skyscrapers, high-strength concrete (HSC) has played an equally important role as normal-strength concrete (NSC) in the industry. In this study, the thermal …

Enhancing hot tooling to forge high-γ ′ superalloys
… cost effectiveness compared to high-γ ′ alloys. Finite element modelling (FEM) was performed to determine optimal range of die temperatures and stresses to handle the pre-heated billets above 1060 °C for the current requirement. For the suitable die core temperature of 750 °C, the predicted …
