Study of Damage Evolution in High Strength Al Alloy using X-Ray Tomography
msra(2011)
摘要
Many micromechanics-based damage models were developed to mimic the macroscopic response of materials through matching measures
such as toughness and failure strain [1]. However, there is a lack of microstructural experimental data to identify the roles
of the initiation, growth and coalescence of voids to damage and failure. This paper is aimed to experimentally investigate
the microstructure of the material and understand the damage processes leading to failure. Experiments using X-Ray Computed
Tomography (XRCT) 3D imaging technique with in-situ loading were conducted [2 - 5].
