The mechanical strength of brittle materials under stress is of prime importance in applications where allowable design stress, lifetime, and reliability are critical issues. A proper analysis should enable an engineer to select an allowable design stress that will permit a brittle component to function for the expected lifetime with an acceptable low probability of failure. It is the purpose of this paper to provide the background for assessing the mechanical reliability of brittle materials under tensile strength.
在允许的设计应力、使用寿命和可靠性是关键问题的应用中，脆性材料在应力作用下的机械强度至关重要。恰当的分析应能使工程师选择一个允许的设计应力，该应力将使脆性部件在预期寿命内正常运行，且失效概率低到可以接受。本文的目的是提供评估脆性材料在拉伸强度下机械可靠性的背景知识。
