Soil investigation is the main key in starting construction. Standard Penetration Test (SPT) and Cone (CPT) are field tests often used to estimate soil parameters for foundation design purposes. The SPT value (N-SPT) shows a correlation between CPT other parameters. At present, there have been many conventional correlations examining these correlations, but nonlinear nature of due very complex ...

Cone penetration resistance in sands with fines contents up to 35% is explored through drained cylindrical cavity expansion simulations with a modified MIT-S1 constitutive model. The constitutive model is calibrated to sands with 0%, 10%, 20%, and 35% low-plasticity fines with data from constant volume direct simple shear, drained and undrained triaxial compression, shear wave velocity, and 1D-...

Using a set of cone penetration test (CPT) records, the current paper develops general framework based on regression analyses to model load-settlement (q-s) behavior shallow foundations resting variety soils ranging from silty clays sands. A three-parameter hyperbolic function is employed rigorously examine obtained q-s curves and determine parameters. Also, results some CPT soundings, includin...

This paper presents an investigation on mechanism of the inclined 1 cone penetration test (CPT) using the numerical discrete element method (DEM). 2 A series of penetration tests with the penetrometer inclined at different angles 3 (i.e., 0°,15°, 30°, 45° and 60°) were numerically performed under µ=0.0 and 4 µ=0.5, where µ is the frictional coefficient between the penetrometer and the soil. 5 T...

Cone penetration testing (CPT) is an extensively utilized and cost effective tool for geotechnical site characterization. CPT consists of pushing at a constant rate electronic cone into penetrable soils recording the resistance to tip (qc value). The measured qc values (after correction pore water pressure) are estimate soil type associated properties based predominantly on empirical correlatio...

The first signs of mobile commerce hype are here. Extremely rapid penetration and growth processes are predicted on the basis of some quick descriptions of mobile technology. The roots of these predictions are often found in markets with a low penetration rate of mobile technology. Nevertheless, it should be clear that without real substance in m-commerce products and services the investments i...

This paper gives an overview on the potentials of numerical simulations for understanding dynamics in laser material processing. After a short introduction into the model, simulation results on several processes like laser beam deep penetration welding, drilling or cutting are presented. Furthermore simulation results are compared with experimentally obtained data.
