Numberical Simulation Of The Interfeace Of Metal Glass Composites’ Deformational And Fracture Behavior

AS a emerging develop specialty materials, their is extensive application prospectsabout mater-glass for its unique physical properties and excellent mechanical properties.However,the mater-glass is lack of plastic deformation, be inclined to brittle fracture, sothe feature of this material severely limits the use. Therefore,the perfection of a matallicglass material plastic strain is one of the focuses of material science at present.Nowadays,The mainstream method is to join the inclusions in metallic glass matrix, the formationof endogenous particle reinforced composites, promote the appearing of shear band forma-tion, so as to improve the plastic strain of material, In this paper, by enhancing thecomposite finite element calculation model based metallic glass particles, a numericalsimulation of the evolution of the interface damage in composite process, providesthe data support for further research of metal glass composites.Firstly, based on the composite interface researchers proposed constitutive relation ofinterface model theory, combined with the meso mechanics analysis method, establisheda composite2D finite element model of a single inclusion, confirming the interfacial bondstrength, loading mode and the interface failure criterion by the experimental date avail-able in the literatures. Subjected to uniaxial tensile simulations by ANSYS software, themodel in the distribution of stress and strain evolution process interface before and afterdamage, and to determine the effect of interface bonding strength on the properties of thematerials.Secondly, through the establishment of failure finite element analysis model and analysisof composite shear, determined the changes of material fracture failure mechianismunder pure shear loading and material general stress.On the evolution of the interfacecrack and propagation process was analyzed.Finally, the establishment of three-dimensional finite element model of composite interfa-ce a qualitative analysis of the geometric size of inclusionsand the volume fraction of theoverall performance of the composite material, in order to establish the constitutiverelationship of particles supported composite interface enhancements.
