One of the common practices in the field of geotechnical engineering is the use of prefabricated vertical drains (PVDs) for ground improvement work. PVDs provides shorter drainage paths to hasten the consolidation process. The performance of the PVDs depend on the spacing, length and characteristics of the PVDs, and the condition of the surrounding subsoil. Three case studies were carried out for the validation process by comparing the actual results from PLAXIS 3D with manual spreadsheet predictions. For this research, PVDs with four 4 different spacings and lengths were constructed at the sites to obtain an optimum geometric design. Based on the analytical calculations, simulation predictions and actual results from the sites, the PVDs installed with a triangular pattern and a spacing of 1.2 m and depth of 36 m achieved the highest settlement reading and consolidation rate in 6 months, with an accuracy of 86.5% for the validation process.

In this study, Al-Mg-Si alloy plates in 4 mm thickness that are particularly used for aerospace and automotive industries were welded using Friction Stir Welding (FSW) method as similar joints with one side pass with parameters of varying tool rotation, weld speed and 2.3 degree tool tilt angle. Tensile tests results showed high yield stress values for FSW joints. Micro Vickers hardness test gave the required result for FSW welded Al-Mg-Si alloy plates. While fatigue test results showed all similar welded joints have fatigue strength close to each other
