过渡区应力集中对复合材料强度试验准确度的影响
THE EFFECT OF STRESS CONCENTRATION ON STRENGTH TEST VALUE OF COMPOSITE MATERIALS
-
摘要: 本文通过推导复合材料强度试验值之准确度与试样破坏部位的关系和破坏发生在试样不同部位的概率,研究了试样过渡区应力集中对复合材料强度试验的影响,讨论了提高试验准确度的措施.Abstract: By deriving the relation between the accuracy of strength test and the failure position of composite materials,as well as the probabilities of specimen breaking at different regions this paper studies the effect of stress concentration test on strength accuracy are test results of composites materials.The methods to improve also discussed.
