Improved knowledge on the deformation pattern around the tip during cone penetration tests is needed. In the present experimental work, the observations and measurements of real soil behavior around a penetrating tip in laboratory tests are presented. Two experimental setups are described: one involving freezing the sample after penetration to preserve deformation patterns and failure features, and one involving computerized tomography. Similar failure patterns were observed in both tests regarding compression directly under the tip and shear structures along the shaft that might be related to a process of accumulation and release of friction during penetration.
