Deformation and failure mechanisms of granular soil around pressurised shallow cavities

Failure mechanism and soil deformation pattern of soil beneath interfering square footings

In this research, the variation of ultimate bearing capacity, failure mechanism and deformation pattern of soil beneath two closely square footings have been studied using numerical methods. It is assumed that the adjacent footings are constructed on the surface of sand. The presented numerical analyses are based on explicit-finite-difference code, FLAC3D. The elasto-plastic behavior of soil is...

Microstructural Investigation of Deformation and Failure Mechanisms in Polypropylene

The automotive industry continues to expand its use of polymeric materials, which provide more cost effective, strength and durability than metals or ceramics. Thus, a better understanding of the mechanical behavior and microstructural characterization of polymers is essential to develop their improved strength and toughness. This paper describes the deformation and fracture study of commercial...

Mechanisms of Dynamic Deformation and Dynamic Failure in Aluminum Nitride

Uniaxial quasi-static, uniaxial dynamic and confined dynamic compression experiments have been performed to characterize the failure and deformation mechanisms of a sintered polycrystalline aluminum nitride using a servohydraulic machine and a modified Kolsky bar. Scanning electron microscopy and transmission electron microscopy (TEM) are used to identify the fracture and deformation mechanisms...
