The basis of linear fracture mechanics is the paper of Griffith which was unrecognized for thirty years. 线性断裂力学的基础是Griffith的论文,但这篇论文三十年来都没有得到承认。
Double-parameter model is one based on corrected linear fracture mechanics and double-k model is based on fictitious crack model. 双参数模型是一种基于修正的线弹性断裂力学的混凝土断裂判断准则。双K参数模型则以虚拟裂缝模型为基础,考虑了混凝土内聚力的作用。
A method for predicting the bending fatigue life of a surface quenched gear is proposed based on two-dimensional linear fracture mechanics and a computer program is developed. 基于二维线性断裂力学理论,提出了一种表面淬火齿轮的弯曲疲劳寿命预测方法,并开发了相应的计算程序。
Therefore, criterion of linear fracture mechanics is not available, and analysis method of non-linear fracture mechanics needs to be used as fracture criterion of concrete. 所以线性断裂力学的判据就不能使用,必须采用非线性断裂力学的分析方法来确定混凝土材料的断裂判据。
Objective To evaluate biomechanical stability of a rigid internal fixation device used for treatment of mandibular linear fracture in dogs. 目的:评价一种新型坚固内固定器械用于治疗犬下颌骨线性骨折的生物力学稳定性。
