In multimodal documents, different types of cohesive or cross-reference link (i.e., signaling) are used in the text to link verbally coded content with the graphical material. In this study, we identify three types of reference, within the framework of previous work on cohesion (Halliday & Hasan, 1976): directive signaling, descriptive signaling, and no signaling in the text to introduce the fi...

hydrodynamics and sediment transport model used to determine the longand short-term stability of dredged material mounds. This technical note (TN) introduces a new cohesive sediment transport submodel for LTFATE, which includes a combined current-wave shear stress calculation and a layered sediment bed model. LTFATE can be accessed via the Internet at the following address: http://www.wes.army....

Free discontinuity problems arising in the variational theory for fracture mechanics are considered.AΓ -convergence proof for an r-adaptive 3Dfinite element discretization is given in the case of a brittle material. The optimal displacement field, crack pattern and mesh geometry are obtained through a variational procedure that encompasses both mechanical and configurational forces. Possible ex...

The expanding ring test of Grady and Benson [20] is taken as a convenient yet challenging validation problem for assessing the delity of cohesive models in situations involving ductile dynamical fracture. Attention has been rescricted to 1100-0 aluminum samples. Fracture has been modelled by recourse to an irreversible cohesive law embedded into cohesive elements. The nite element model is thre...

We formulate differential cohomology and Chern-Weil theory the theory of connections on fiber bundles and of gauge fields abstractly in the context of a certain class of higher toposes that we call cohesive. Cocycles in this differential cohomology classify higher principal bundles equipped with cohesive structure (topological, smooth, synthetic differential, supergeometric, etc.) and equipped ...

Bin Zhou, M. D. Thouless, and S. M. Ward Department of Mechanical Engineering Department of Material Science and Engineering University of Michigan Ann Arbor, MI, 48109 Scientific Research Laboratory Ford Motor Company Dearborn, MI, 48124 Abstract A methodology for determining the cohesive facture parameters associated with pull-out of spot welds is presented. Since failure of a spot weld by pu...

A well-controlled and minimal experimental scheme for dynamic fracture along weak planes is specifically designed for the validation of large-scale simulations using cohesive finite elements. The role of the experiments in the integrated approach is two-fold. On the one hand, careful measurements provide accurate boundary conditions and material parameters for a complete setup of the simulation...
