This paper presents a review of creep deformation and rupture mechanisms of low Cr-Mo alloy for the development of its creep damage constitutive equations under lower stress. The most popular Kachanov-Robatnov-Hayhurst (KRH) formulation was not necessarily developed and calibrated for low stress and cannot depict the creep strain accurately under multi-axial state of stress due to the three-dim...

his paper introduces a test methodology to examine the urability of surface mount interconnects under impact oading when a portable electronic product is dropped. onventional testing approaches that consider the agnitude of loading (total impact energy, impact direction, nd number of impacts) as the governing criterion for amage accumulation, typically report difficulties in orrelating with imp...

The mechanical behavior of newly developed composite materials is dependent on several underlying microstructural phenomena. In this research, a periodic 2D geometry cast X8CrMnNi16-6-6 steel and 10% zirconia virtually constructed by adopting attributes from literature. A physics-based crystal plasticity model with ductile damage criterion used for defining the austenitic matrix. particles are ...

In the given paper we investigate the problem of constructing a simulation model for the optimization of current stock of divisible productions in the warehouse. Criterion of optimization is minimum of average expenses for goods holding, ordering and losses from deficit and damage to the goods per time of season. The ExtendSim 8 package has been used as the means of simulation. The numerical ex...

Introduction sy is the only bacterial disease chary the causative organisms infecting the nerves. Clinical or histological tion of peripheral nerve involvement in lesion or elsewhere is an essential criterion for leprosy. The consequences ral nerve involvement result in great and social stigma associated with twithstanding all this, our knowledge of lvement and damage in leprosy is d our abilit...

The existence or nonexistence of a percolation threshold on power law correlated graphs is a fundamental question for which a general criterion is lacking. In this work we investigate the problems of site and bond percolation on graphs with degree correlations and their connection with spreading phenomena. We obtain some general expressions that allow the computation of the transition threshold...

A continuum-level, dual internal state variable, thermodynamically based, work potential model, Schapery Theory, is used capture the effects of two matrix damage mechanisms in a fiber-reinforced laminated composite: microdamage and transverse cracking. Matrix microdamage accrues primarily in the form of shear microcracks between the fibers of the composite. Whereas, larger transverse matrix cra...

The present work describes a multiscale methodology which has been developed for modeling of impact damage in the laminated composite structures. The methodology employs the High Fidelity Generalized Method of Cells (HFGMC) micromechanical model for the prediction of the local stress and strain fields, within the representative unit cell of the unidirectional composite material. The Mixed Mode ...

The identification of damage in structural systems, including characterization of damage location and severity, is of extreme interest to the structural engineering profession. To date, many damage detection methods have been proposed that utilize global structural response measurements in the time and frequency domains to hypothesize the existence of structural damage. The accuracy and robustn...

The goal of this work is to predict ductile failure pipe-ring notched AISI 316L specimens, where notches mimic the geometry corrosion defects. Uncoupled damage models are used that end. Johnson-Cook and Lou-Huh criteria calibrated. uncoupled calibrated using experimental results from testing specimens. Calibration was achieved a hybrid experimental-numerical approach. Six notch shapes studied. ...
