In this paper, a new procedure is used to find the bearing capacity of single piles and cone penetration resistance in soils. Although the procedure is mainly applicable to clay and sand using any plasticity model, this paper deals only with steady penetration in Sand. Cylindrical cavity expansion around the probe in a calibration chamber is modeled by finite element method using the HUJEUX elasto-plastic multi-mechanism model. The penetration resistance (qc) is related to cylindrical cavity expansion pressure limit (pL) using the method of Salgado et al. (1997). This procedure is tested using the results found in 3S/IMG calibration chamber. In this article the word "penetrometer" refers to both pile and cone.
