The　combustion　and　fluidization　behavior　of　biomass　depend　on　the　physical　properties　(size,　morphology,　and　density)　and　mechanical　performances　(elastic　modulus,　Poisson＇s　ratio,　tensile　strength　and　failure　strain),　but　their　quantitative　models　have　rarely　been　focused　in　previous　researchers.　Hence,　a　static　image　measurement　for　particle　physical　properties　is　studied.　Combining　the　uniaxial　tension　and　digital　image　correlation　technology,　the　dynamic　image　measurement　method　for　the　mechanical　properties　is　proposed.　The　results　indicate　that　the　average　roundness,　rectangularity,　and　sphericity　of　present　biomass　particles　are　0.2,　0.4,　and　0.16,　respectively.　The　equivalent　diameter　and　density　obey　the　skewed　normal　distribution.　The　tensile　strength　and　failure　stress　are　sensitive　to　stretching　rate,　fiber　size　and　orientation.　The　distribution　intervals　of　elastic　modulus　and　Poisson＇s　ratio　are　30-600　MPa　and　0.25-0.307,　respectively.　The　stress-strain　curves　obtained　from　imaging　experiments　agree　well　with　the　result　of　finite　element　method.　This　study　provides　the　operating　parameters　for　the　numerical　simulation　of　particles　in　the　fluidized　bed　and　combustor.　Furthermore,　the　computer　vision　measurement　method　can　be　extended　to　the　investigations　of　fossil　fuels.
