Dynamic Crack Initiation in Ductile Steels
The goal of the work presented here is to study dynamic crack initiation in ductile steels "NiÐCr steel and 293 stainless steel# at di}erent loading rates and to establish appropriate dynamic failure criteria[ A variety of infrared and visible optical methods and high!speed photography are used in this study[ Precracked steel specimens are subjected to dynamic three!point bend loading by impact...
متن کاملSubstructure Model for Concrete Behavior Simulation under Cyclic Multiaxial Loading
This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...
متن کاملPrediction of Crack Initiation Direction for Inclined Crack Under Biaxial Loading by Finite Element Method
This paper presents a simple method based on strain energy density criterion to study the crack initiation angle by finite element method under biaxial loading condition. The crack surface relative displacement method is used to eliminate the calculation of the stress intensity factors which are normally required. The analysis is performed using higher order four node quadrilateral element. The...
متن کاملDetermining the Critical Intensity for Crack Initiation in Concrete Arch Dams by Endurance Time Method
This study aims at determining the critical seismic intensity at which cracks are expected to develop in a concrete arch dam. This intensity is referred to as crack initiation intensity. The crack initiation intensity measure implies that earthquakes with the intensity measure higher than this value are expected to induce cracks in the arch dam. This quantity is an indicator for seismic evaluat...
متن کاملPredicting Depth and Path of Subsurface Crack Propagation at Gear Tooth Flank under Cyclic Contact Loading
In this paper, a two-dimensional computational model is proposed for predicting the initiation position and propagation path of subsurface crack of spur gear tooth flank. In order to simulate the contact of teeth, an equivalent model of two contacting cylinders is used. The problem is assumed to be under linear elastic fracture mechanic conditions and finite element method is used for numerical...
