One　of　the　challenges　in　the　applications　of　instrumented　indentation　is　to　simultaneously　measure　elastic　modulus　and　Poisson＇s　ratio　of　homogeneous,　isotropic　materials.　This　work　proposes　empirical　equations　for　simultaneous　calculation　of　elastic　modulus　and　Poisson＇s　ratio　of　bulk　metallic　glasses　(BMGs)　from　the　ratio　of　the　short　diagonal　length　to　the　long　diagonal　length　and　the　area　of　the　Knoop　imprint.　The　parameters　presented　in　the　empirical　equations　are　determined　first　by　Knoop　microhardness　tests　of　24　BMGs,　whose　elastic　moduli　and　Poisson＇s　ratios　are　measured　by　resonant　ultrasound　spectroscopy.　These　empirical　equations　are　further　validated　by　the　Knoop　microhardness　tests　of　other　3　BMGs,　which　yield　elastic　moduli　and　Poisson＇s　ratios　in　good　accordance　with　the　corresponding　ones　available　in　the　literature　and　with　the　results　from　nanoindentation　tests.　This　work　opens　a　new　venue　of　Knoop　microhardness　test　as　an　economical　and　efficient　method　to　measure　both　elastic　modulus　and　Poisson＇s　ratio　of　BMGs.　©　2024
