This paper presents a new micromechanical model for a collection of cohesive zone models embedded between each mesh of a finite element-type discretization. It aims to forth fully extend the previous linear results of [1] to the calibration of damageable cohesive parameters (cohesive peak stress, critical opening displacement, cohesive energy, etc). The main idea of the approach consists in rep...

1 The Effect of Cohesive-Law Parameters on Mixed-Mode Fracture R. B. Sills and M. D. Thouless Department of Mechanical Engineering Department of Materials Science & Engineering University of Michigan Ann Arbor, MI 48109-2125, USA Abstract Cohesive-zone models of fracture provide a framework that allows a smooth transition between a strength-based approach to fracture and an energy-based approac...

In this paper Cohesive Zone Model (CZM) concepts are applied in order to study mode I fracture in a pre-cracked bonded Double Cantilever Beam (DCB) specimen. A cohesive surface element is implemented in a Finite Element commercial code using intrinsic cohesive zone models: exponential, bilinear and trapezoidal traction-separation laws. The sensitivity of cohesive zone parameters in predicting t...

Discourses are defined as ideas conveyed by humans through language using a series of sentences in co-text and context. Co-text is the cohesive coherent relationship between written words, phrases, sentences, paragraph. Generally, contexts understood more broadly even beyond boundaries language, therefore, it considered non- linguistic. It also circumstances behind an idea used reference for un...

In finite element analysis (FEA) models of cemented hip reconstructions, it is crucial to include the cement-bone interface mechanics. Recently, a micromechanical cohesive model was generated which reproduces the behavior of the cement-bone interface. The goal was to investigate whether this cohesive model was directly applicable on a macro level. From transverse sections of retrieved cemented ...

Finite element calculations of dynamic fracture based on embedding cohesive surfaces in a continuum indicate that the predictions are sensitive to the cohesive law used. Simulations were performed on a square block in plane strain with an initial edge crack loaded at a constant rate of strain. Cohesive laws that have an initial elastic response were observed to produce spontaneous branching at ...

From the ocean of text data, Extracting the important and query based text is a big NLP problem. It is a difficult task, as it requires mining text content in shortest answer length accurately and efficiently. This paper describes an attempt toward solving this problem with an intelligent approach. The proposed idea is based on the human intelligence-once a document is seen; it takes less time ...

In this paper, we present a new approach to writing tools that extends beyond the rudimentary spelling and grammar checking to the content of the writing itself. Linguistic methods have long been used to detect familiar lexical patterns in the text to aid automatic summarization and translation of documents. We apply these methods to determine the quality of the text and implement new technique...
