مقاله Damage evolution and thermal coupled effects in inelastic solids : تی پی بین

خلاصه مقاله

Mechanical degradation and ductile failure in metal forming operations can be successfully modelled using Continuum Damage Mechanics. In addition to elastic–plastic deformations, heat transfer affects material behaviour, imposing further effects upon damage evolution. This paper addresses modelling aspects and presents a numerical discussion of the coupled effects between ductile damage and temperature evolution. The heat transfer problem is formulated based on a transient heat conduction approximation, in which heat transfer at the free surfaces and heating due to dissipation of the inelastic work are accounted for. Damage is modelled using an elastic–plastic fully coupled approximation, in which differences in tensile and compressive stress states are included.

International Journal of Mechanical Sciences

The International Journal of Mechanical Sciences (IJMS) is an international forum for the publication and dissemination of original work which contributes to greater scientific understanding of the main disciplines underpinning the mechanical, civil and material engineering sciences. Original contributions providing insight into the use of analytical, computational (e.g. FEM, BEM, mesh-free methods and others) modelling methods for rigid body mechanics (e.g. dynamics, vibration, stability), structural mechanics, metal forming, behaviour and application of advanced materials (metals, composite, cellular, smart etc.), impact mechanics, strain localization and other effects of nonlinearity (e.g. large deflections, plasticity, fracture etc.), fluid mechanics (external and internal flows), tribology, thermodynamics and materials processing generally form the core of the journal contents.
