• ### APPLIED FRACTURE MECHANICS

The book "Applied Fracture Mechanics" presents a collection of articles on application of fracture mechanics methods to materials science, medicine, and engineering. In thirteen chapters, a wide range of topics is discussed, including strength of biological tissues, safety of nuclear reactor components, fatigue effects in pipelines, environmental effects on fracture among others. In addition, the book presents mathematical and computational methods underlying the fracture mechanics applications, and also developments in statistical modeling of fatigue.

• ### Introduction to Fracture Mechanics

Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.In modern materials science, fracture mechanics is an important tool in improving the mechanical performance of materials and components.

(BQ) Part 2 book "Advanced mechanics of materials" has contents: The thick wall cylinder, elastic and inelastic stability of columns, flat plates, stress concentrations, fracture mechanics, progressive fracture, contact stresses, time dependent deformation.

• ### Dual integrals in non-linear fracture mechanics

The analysis of the dissipation shows that the thermodynamical force associated with the evolution of a crack is an energy release rate, form of which depends on the presence or not of mechanical discontinuities. This energy release rate is given as an integral based on free or complementary energy. We analyse the invariance of such integrals and we discuss the obtained results in elastoplasticity.

• ### Mechanical Behaviour of Engineering Materials

There is a vast multitude of materials with strongly differing properties. A copper wire, for instance, can be bent easily into a new shape, whereas a rubber band will snap back to its initial form after deformation, while the attempt to bend a glass tube ends with fracture of the tube. The strongly differing properties are reflected in the application of engineering materials – you would neither want to build cars of glass nor rubber bridges. The multitude of materials enables the engineer to select the best-suited one for any particular component.

• ### Descartes on Forms and Mechanisms

René Descartes gives few philosophical arguments to directly support his rejection of forms in favor of mechanisms . Moreover, the scattered reasons he offers in his corpus are cryptic and hard to unpack. Hence I will draw on Descartes’ intellectual context to reconstruct his reasoning and shed light on his historic elimination of Scholastic Aristotelian substantial forms from the physical world.

• ### Calculation of fracture mechanic parameters via fem for some cracked plates under different loads

This paper describes some results in analyzing cracked plates via FEM based on the procedures in CASTEM 2000 [1]. The basic methods for computing the crack parameters by the finite element analysis are presented. Some programs written by GIBIAN languages to solve problems for cracked plates are given.

• ### Prediction of the cohesive crack growth in concrete beams in bending by mean of fracture mechanics and the finite element method

The text presents the theoretical base for the construction of the program CGPTROl. The fictitious crack model and the finite element method are employed for analyzing. This program is created to investigate two-dimensional models for the initiation and growth of the I-mode crack in notched beams in bending. The final result of the fradtu"e analysis is ·the load-deflection diagram for the prediction of the cohesive crack growth in concrete notched beam in bending.

• ### Liquid-Gas Relative Permeabilities in Fractures: Effects of Flow Structures, Phase Transformation and Surface Roughness

Fractures are ubiquitous in the brittle lithosphere in the upper part of earth’s crust. They play a critical role in the transport of fluids. Moreover, all major discovered geothermal reservoirs and a considerable number of petroleum reservoirs are in fractured rocks. This restates the importance of studying multiphase flow behavior inside the opened fracture space. From the engineering point of view, a rock fracture as defined here is simply a complex-shaped cavity filled with fluids or solid minerals. Therefore it is understood to include cracks, joints, and faults.

• ### Simulating fatigue crack growth in spiral bevel gears

This research project was motivated by the possibility of using fracture mechanics to assist in optimizing gear design. The primary goal is to develop a state-of-the-art capability for modeling three-dimensional crack propagation in gears using boundary element method, finite element method, and fracture mechanics. It is being conducted by a grant between Cornell University and the NASA-Glenn Research Center (formerly known as Lewis Research Center).

• ### Itch Basic Mechanisms and Therapy

Over the past decade, there has been a vast explosion in new information relating to the art and science of dermatology as well as fundamental cutaneous biology. Furthermore, this information is no longer of interest only to the small but growing specialty of dermatology. Scientists from a wide variety of disciplines have come to recognize both the importance of skin in fundamental biological processes and the broad implications of understanding the pathogenesis of skin disease. As a result, there is now a multidisciplinary and worldwide interest in the progress of dermatology....
