Additive Manufacturing offers real opportunities in Thales, since it enables a flexible and cost-effective production of metallic components directly from 3D digital data model. The manufacture the parts, layer by layer, allows building more complex geometries adding new functionalities or reducing weight. products Thales can be competitive attractive. Studying analysing mechanical properties such samples is essential. In order to able choose eligible design these parts ensure their...
ABSTRACT This paper presents a global approach to the design of structures that experience thermomechanical fatigue loading, which has been applied successfully in case cast‐iron exhaust manifolds. After presentation context automotive industry, important hypotheses and choices this approach, based on thermal 3D computation, an elastoviscoplastic constitutive law dissipated energy per cycle as damage indicator associated with failure criterion, are first pointed out. Two particular aspects...
The purpose of this paper is to define a low cycle fatigue criterion in order predict the failure engineering structures. major problem defining predictive that it should be applicable for structures submitted complex multiaxial thermo-mechanical loadings but identifiable from simple experiments on specimens. After short critical review principal criteria used will shown dissipated energy per permits correlation isothermal and anisothermal results obtained silicon molybdenum cast iron case...
ABSTRACT In this paper thermomechanical fatigue assessment in the automotive industry is discussed. The design strategy based upon a consistent approach of loading, mechanical constitutive law material, damage parameters and strength criteria. good understanding these different steps allows one to perform predictive calculations parts subjected loading. main hypotheses modelling choices are presented results illustrated by series computations on real 3D structures. Cracked area lifetime...
Abstract The aim of this work is to analyse the strain field heterogeneity in an aluminium alloy subjected low‐cycle fatigue at high temperature. In cylinder heads produced by a lost‐foam casting process, microstructure studied consists hard intermetallic phases and large gas microshrinkage pores. order study influence complex 3D on crack initiation propagation 250 °C, experimental protocol using laboratory synchrotron tomography, finite element simulation new digital volume correlation...
