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 tests (CPTs) can provide highly accurate and detailed information characteristics relevant to the stiffness, strength, consolidation of tested geomaterials, but they do not directly recover real soil samples. Thus, when CPT results are applied classification, experience-based classification charts or tables generally used. However, such have inherent drawback being derived from...

introduction: this in vitro study aims to evaluate the coronal and apical sealing ability of gutta-percha (gp) root filling used with either mineral trioxide aggregate (mta), new endodontic cement (nec) or ah26 as filler/sealers. materials and methods: forty eight single-rooted extracted teeth were selected, decoronated and then instrumented. samples were randomly divided into three experimenta...

Artificial neural networks (ANNs) are often used recently by researchers to solve complex and nonlinear problems. Standard penetration test (SPT) cone (CPT) field tests that obtain soil parameters. There have been many previous studies examined the value obtained through SPT with CPT test, but research carried out still uses equations linear. This will conduct an estimated of on cohesive using ...
