Abstract: This paper explores the standard penetration test (SPT) hammer-anvil behavior and investigates the effect of secondary impact on SPT energy and sampler penetration. It is observed that the hammer-anvil behavior after the ...

Abstract: Because an aircraft gas turbine operates under various flight conditions that change with altitude, flight velocity, and ambient temperature, the performance estimation that considers the flight ...

Abstract: In this study, rubber-sand particle mixtures are investigated to understand their stress-deformation and elastic modulus characteristics. Specimens are prepared with various size ratios, sr

Abstract: The assessment of the shear stiffness of dredged soft ground and soft clay is extremely difficult due to soil disturbances caused during sampling and field access. Several in situ methods such as spectral analysis of surface ...

Abstract: Unconfined compressive strength (qucs) and maximum shear modulus (Gmax), which are essential properties of grouted sands for quality control and stable design, exhibit a nonlinear behavior with curing time that makes it ...
