Near-field dynamics of parallel twin jets in cross-flow by Zang, Bin, New, Tze How

“…Further examination into the Reynolds shear stresses indicates that there exists substantial flow shear stress as the pair of inner vortices interacts, which yields higher entrainment level of the cross-flow fluid in regions adjacent to the symmetry plane. …”

Experimental and numerical investigation of adhesively bonded kfrp/steel double strap joints incorporating eggshell powder-toughened epoxy adhesive by Chia Lia Yip, Chia Lia Yip, Sugiman Sugiman, Sugiman Sugiman, Desmond Chin, Desmond Chin, Ahmad, Hilton

“…Moreover, epoxy resin is widely used as a matrix of composites and adhesives; however, it has low shear strength. Improvement of epoxy properties is therefore required, for example, by incorporating biofiller such as eggshells from household waste, which contain calcite, to improve its shear strength. …”

Effects of deep excavation on pile behaviour by Vindy

“…This report will focus on the effect of deep excavation on adjacent pile behaviour.Parametric studies using plane strain and three-dimensional finite element analyses programs, PLAXIS 2D and PLAXIS 3D Foundation are carried out to investigate the various aspects that influence the pile responses such as the effect of wall stiffness (flexible, medium and stiff walls), pile diameter (0.6 m and 1 m diameter), distance from pile to the primary wall (1 m and 5 m), and undrained shear strength of the soil which is assumed to increase linearly with depth of excavation. …”
