TL;DR: In this article, a thorough finite element (FE) parametric study of sheet pile wall deflections caused by deep dynamic compaction (DDC) was presented, and the effects of several parameters which may affect the wall deflection were investigated.

TL;DR: In this article, a numerical simulation of the ignition of structurally heterogeneous condensed material by a small single particle heated to high temperature, a typical limited heat content source of is performed within the framework of a solidphase ignition model.
Abstract: A numerical simulation of the ignition of structurally heterogeneous condensed material by a small single particle heated to high temperature, a typical limited heat content source of is performed within the framework of a solidphase ignition model. The effe ct of the depth of embedment of the heated particle into the subsurface layer of the metallized material on the integral characteristics of the ignition is examined.

TL;DR: In this paper, an analytical approach was proposed to predict the maximum pull-out load of steel bar from concrete, which was then related to the local fracture energy at the shear crack-tip region.

TL;DR: The recently proposed particle finite element method is employed, which combines the robustness of classical continuum mechanics formulations in terms of representing complex aspects of the material constitutive behavior, with the effectiveness of discrete element methods in simulating ultralarge deformation problems.
Abstract: We investigate numerically the mechanisms governing horizontal dragging of a rigid cylinder buried inside granular matter, with particular emphasis on enumerating drag and lift forces that resist cylinder movement. The recently proposed particle finite element method is employed, which combines the robustness of classical continuum mechanics formulations in terms of representing complex aspects of the material constitutive behavior, with the effectiveness of discrete element methods in simulating ultralarge deformation problems. The investigation focuses on the effect of embedment depth, cylinder roughness, granular matter macromechanical properties, and of the magnitude of the cylinder's horizontal displacement on the amplitude of the resisting forces, which are discussed in light of published experimental data. Interpretation of the results provides insight on how the material flow around the cylinder affects the developing resistance, and a mechanism is proposed to describe the development of a steady-state drag force at large horizontal movements of the cylinder.

TL;DR: In this article, a vertical surcharge was proposed to increase the resistance of pile columns to horizontal loads in clays with relative embeddings < 15.1. But the principle of independence of the action of forces in the general case is not applicable to calculation of column columns.
Abstract: 1. The principle of independence of the action of forces in the general case is not applicable to calculation of pile columns with relative embedment < 15. A vertical surcharge can somewhat decrease (in weak saturated soils) or increase (in clays of very stiff consistency) the resistance of pile columns to horizontal loads. In the investigated saturated soils, the bearing capacity decreased by no more than 15%, and in very stiff slump-prone soils it increased by a factor of 1.9.
