Investigation on the Triaxial Mechanics Properties of Resin Sands at Elevated Temperature
-
摘要: 利用新研制的型砂高溫三軸測試手段,首次測定了常用樹脂型砂在圍壓作用下的高溫三軸力學性能.試驗結果揭示了傳統研究方法的不足.并依據修正的強度理論對型砂高溫力學特性提出新的解釋.

Abstract: The triaxial mechanics properties of a resin sand at elevated temperature are revealed through the recently developed trixaial apparatus for moulding sands.The traditional test method is found unreasonable by comparison with the present results;and the new comprehension to the high temperature behavior of moulding sand is given with the modified strength theory. -
