Abstract The cohesive element approach is getting increasingly popular for simulations in which a large amount of cracking occurs. Naturally, robust representation fragmentation mechanics contingent to an accurate description dissipative mechanisms form and branching. A number law models have been proposed over the years these can be divided into two categories: laws that are initially rigid initial elastic slope. This paper focuses on law, shown successfully capture crack branching...
Reinforced concrete (RC) marine piles usually suffer from local stiffness deterioration caused by chloride attack in splash and tidal zones. Moreover, pre-existing cracks defects at the steel–concrete interface lead to nonuniformly localized corrosion, which has seldomly been discussed. In this study, effects of corrosion on lateral behaviours were experimentally studied. The electrochemical erosion (LECE) technique was employed, level represented number corroded steel bars length sections....
Abstract In this work, a long surface wave plasma column is generated using high power pulse-modulated microwave in argon at atmospheric pressure. The temporal evolutions of the electron density and temperature are diagnosed by optical emission spectroscopy. It found that intensity peaks correspond to nodes standing waves where local electric field reduced, rather than antinodes, which contrast with low pressure discharges. reasons for behavior discussed considering excitation balance...
A coupled plastic damage model with two scalars is proposed to describe the nonlinear features of concrete. The constitutive formulations are developed by assuming that can be represented effectively in material compliance tensor. Damage evolution law and coupling described using framework irreversible thermodynamics. plasticity part without effective stress concept. yield function based on true adopted hardening functions, one for tensile loading history other compressive history. To couple...
To study the propagating behavior of a dynamic crack in brittle materials, an experimental technique was developed that measures propagation speed fast preloaded strip. The specimen is rectangular PMMA plate clamped by two heavy steel fixtures are attached to MTS test machine. After tensile loaded prescribed load level, sharp initiated at middle point on one side specimen. Due brittleness material, propagates quickly across velocity measured using equally spaced conductive lines were painted...
The adiabatic shear bands (ASB) of the thick-walled cylinder have been studied by many researchers in recent years. onset and evolutions multiple failure metal under explosive loadings are affected factors such as characteristics impulsive loadings, dynamic behavior materials, etc. In this work, a tube compression driven electro-magnetic forces is introduced, which enables to carry out experiments spontaneous evolution tube. FEM simulation was conducted investigate process strain...
As the accident of a vessel impacting bridge pier will result in serious disaster, such as fall, ship sink and polluting environment, technology method have been investigated to prevent protect bridges from collisions. An adaptive arresting net crashworthy device has developed for protecting non-navigable channel piers against collisions, which consists mooring floating boats, cable anchors, buckets, net, triggering wire rope constant resistant force cables. When impacts device, first head...
A new experimental technology based on the Split Hopkinson Pressure Bar (SHPB) is developed for conducting expanding ring tests. The technique useful studies of dynamic tensile deformation and fracture (fragmentation) properties ductile metallic materials. loading fixture includes a hydraulic cylinder filled with incompressible fluid, which pushed by piston connected to input bar. As liquid driven, it transfers pressure specimen, compressing specimen in radial direction. approximately...
