  1. 1. Elastoplasticity of Grey Cast Iron FE-Algorithms and Biaxial Experiments

    Författare :Hans E. Hjelm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biaxial experiments; multiaxial elastoplastic behaviour; graphite flakes; FE-codes; hardening behaviour; graphitic grey cast iron;

    Sammanfattning : This thesis focuses on multiaxial elastoplastic behaviour of graphitic grey cast iron with the aim to provide physically appropriate and numerically reliable constitutive relations for use in FE-codes. To achieve this goal, this work is divided into three parts: Biaxial experiments are performed on thin cruciform specimens. LÄS MER

    Sammanfattning : An ontology is a knowledge-representation structure, where words, terms or concepts are defined by their mutual hierarchical relations. Ontologies are becoming ever more prevalent in the world of natural language processing, where we currently see a tendency towards using semantics for solving a variety of tasks, particularly tasks related to information access.
