这是一个例子，展示了脆性理论[哈德，N.A.，格里菲斯方程和脆性理论。 Bygningstatiske Meddelelser, 1995, 66(2–3), 24–84 和 Harder, N.A., 断裂力学应力软化模型中的脆性理论, Enngng Fracture Mech., 1996, 53(4), 527–534] 在工程实践中可能很有用。推导了极限载荷的尺寸效应定律。尺寸效应仅归因于脆性，所有其他效应，例如不考虑材料参数的随机变化。因此，分析结果与实验室测试结果之间可能存在一些微小偏差。
This is one example showing how the Theory of Brittleness [Harder, N. A., Griffith's equation and theory of brittleness. Bygningstatiske Meddelelser, 1995, 66(2–3), 24–84 and Harder, N.A., Theory of brittleness in stresssoftening models of fracture mechanics, Engng Fracture Mech., 1996, 53(4), 527–534] can be useful in engineering practice. A size effect law for ultimate load is derived. The size effect is due to brittleness only, all other effects, e.g. stochastical variation of material parameters, are not considered. Therefore, some minor deviations between analytical results and results obtained from laboratory tests may be expected.
