Fracture and singularities of the mass-density gradient field∗
نویسنده
چکیده
A continuum mechanical theory of fracture without singular fields is proposed. The primary contribution is the rationalization of the structure of a ‘law of motion’ for crack-tips, essentially as a kinematical consequence and involving topological characteristics. Questions of compatibility arising from the kinematics of the model are explored. The thermodynamic driving force for crack-tip motion in solids of arbitrary constitution is a natural consequence of the model. The governing equations represent a new class of pattern-forming equations.

Investigating the Decreased Bone Density Prevalence in People with Common Risk Factors Referred to Al-Zahra Educational-Medical Center in Isfahan City Years of 2018 and 2019
Introduction: Osteoporosis is a disease in skeletal system that is recognized by a lack of bone density and degeneration of bone tissue and can lead to increase the risk of bone fracture or even death. So, this study was conducted to determine the prevalence of decreased bone density in people with common risk factors referred to Al-Zahra Educational-Medical Center in Isfahan City years 2018-20...
متن کاملImproving the accuracy of fracture modeling in carbonate reservoirs X-field in SW of Iran
Fracture modeling is one of the most important steps in the study of fractured reservoirs. Due to the high cost of imaging logs and their absence in most wells of the study area, it is often attempted to use other available data to detect fractures. This paper attempts to investigate the relationship between the lithology and fractures of rocks. For this purpose, the Image, Neutron, Density, Li...

An analytical investigation is conducted to study the unsteady free convection heat and mass transfer flow through a non-homogeneous porous medium with variable permeability bounded by an infinite porous vertical plate in slip flow regime while taking into account the thermal radiation, chemical reaction, the Soret number, and temperature gradient dependent heat source. The flow is considered u...

Computed Magnetic Gradient Tensor (CMGT) includes the first derivatives of three components of magnetic field of a body. At the eigenvector analysis of Gravity Gradient Tensors (GGT) for a line of poles and point pole, the eigenvectors of the largest eigenvalues (first eigenvectors) point precisely toward the Center of Mass (COM) of a body. However, due to the nature of the magnetic field, it i...
