摘要: Abstract Finite element analyses were carried out to study the stress distribution in particulate Al 2 O 3 -reinforced metal–matrix composites subjected external compressive and tensile load as a function of interfacial bonding strength. Unit cells containing hard particles with either weak or rigid interfaces multi-linear kinematic hardening matrix used determine corresponding flow The effect strength on response tension compression was also examined. predictions cracking mode behavior based FEM found be reasonable agreement observations 5083Al–10vol.% Al–5Mg–10vol.% composites.
