Estimation of Penetration Depth Using Acceleration Signal Analysis for Underwater Free Fall Cone Penetration Tester

Consistent penetration depth estimation for deformable collision response

Penalty approaches can be used to efficiently resolve collisions of dynamically simulated rigid and deformable objects. These approaches compute penalty forces based on the penetration depth of intersecting objects and there exist many algorithms for estimating the exact penetration depth. However, in discrete-time simulations, this information can cause non-plausible collision responses in cas...

Continuous penetration depth

We present a new measure for computing continuous penetration depth between two intersecting rigid objects. We generate a set of samples in the configuration space, precompute an approximation of the contact space for two intersecting objects using binary classification techniques, and construct a bijective mapping between the spherical space and the precomputed contact space. For a given in-co...

Efficient Penetration Depth Approximation using Active Learning

Given two objectsA andB, we denote their configuration space as C-space and each configuration or point in C-space corresponds to relative configuration (i.e., position and orientation) of A w.r.t B. In the rest of the paper, we assume that A is movable and B is fixed. For 2D objects, C-space has 2 degrees of freedom (DOF) if A can only undergo translation motion, and 3-DOF if we take into acco...

A Method for Predicting Pile Capacity Using Cone Penetration Test Data

The massive construction in poor lands has encouraged engineers to use deep foundations in order to transfer superstructure loads to the subsoil. Since soil excavation, sampling, and laboratory testing as a part of site investigation are relatively difficult, in-situ tests such as cone penetration test (CPT) as a very informative test may be recommended. The CPT has been widely used in engineer...
