By Somnath Ghosh
As multi-phase metal/alloy platforms and polymer, ceramic, or steel matrix composite fabrics are more and more getting used in undefined, the technology and know-how for those heterogeneous fabrics has complicated swiftly. through extending analytical and numerical types, engineers can learn failure features of the fabrics ahead of they're built-in into the layout procedure. Micromechanical research and Multi-Scale Modeling utilizing the Voronoi phone Finite aspect strategy addresses the most important challenge of multi-scale failure and deformation of fabrics that experience complicated microstructures. The book presents a complete computational mechanics and fabrics science–based framework for multi-scale research.
The concentration is on micromechanical research utilizing the Voronoi mobile finite aspect approach (VCFEM) built through the writer and his examine team for the effective and exact modeling of fabrics with non-uniform heterogeneous microstructures. whereas the themes coated within the e-book surround the macroscopic scale of structural elements and the microscopic scale of constituent heterogeneities like inclusions or voids, the overall framework will be prolonged to different scales in addition.
The publication provides the most important parts of the multi-scale research framework in 3 elements. facing multi-scale picture research and characterization, the 1st a part of the e-book covers second and 3D image-based microstructure iteration and tessellation into Voronoi cells. the second one half develops VCFEM for micromechanical pressure and failure research, in addition to thermal research, of prolonged microstructural areas. It examines a variety of difficulties solved via VCFEM, from warmth move and stress-strain research of elastic, elastic-plastic, and viscoplastic fabric microstructures to microstructural harm types together with interfacial debonding and ductile failure. constructing the multi-scale framework for heterogeneous fabrics with and with out harm, the 3rd a part of the ebook discusses adaptive concurrent multi-scale research incorporating bottom-up and top-down modeling.
Including numerical examples and a CD-ROM with VCFEM resource codes and input/output documents, this ebook is a necessary reference for researchers, engineers, and execs concerned with predicting the functionality and failure of fabrics in structure-materials interactions.
