Piezoelectric single crystal based one-dimensional phased array for breast tissue imaging
Published 2024“…In this thesis, I propose a conformable ultrasound breast patch (cUSBr-Patch) consisting of a one-dimensional (1D) phased array and a nature-inspired patch design, which offers large-area, deep tissue scanning and multi-angle, repeatable breast imaging while avoiding the drawbacks of conventional ultrasound imaging technologies. I used a Yb/Bi-doped PIN-PMN-PT single crystal as the active element due to its superior piezoelectric properties (d33 = 2,800 pC/N, εr = 7,000, k33 = 0.93). …”

Local-flexural interactive buckling of S690 high strength steel slender welded I-section columns: testing, modelling and design
Published 2022“…A testing programme, adopting two S690 high strength steel slender welded I-sections, was firstly conducted and included initial geometric imperfection measurements and ten pin-ended column tests. The testing programme was accompanied by a numerical modelling programme, where finite element models were developed and validated against the test results and then employed to perform parametric studies to generate further numerical data over a wide range of cross-section dimensions and member effective lengths. …”
