Hashin model

Web对CFRP短管进行轴压试验，重点研究碳纤维增强复合材料的刚度、极限强度以及细观破坏模式。基于Hashin破坏准则进行二次开发，采用ANSYS有限元软件对试验过程进行了数值模拟，数值结果表明，Hashin破坏准则可以较好地预测CFRP复合材料破坏时的极限承载力。 These are interacting failure criteria where more than one stress components have been used to evaluate the different failure modes. These criteria were originally developed for unidirectional polymeric composites, and hence, applications to other type of laminates and non-polymeric composites have significant approximations. Usually Hashin criteria are implemented within two-dimensional classical lamination approach for point stress calculations with ply discounting as th…

WebEngineering Computer Science Hashing is a technique to convert a range of key values into a range of indexes of an array. Load Factor is a measure of how full the hash table is allowed to get before its capacity is automatically increased which may cause a collision. When collision occurs, there are two simple solutions: Chaining and Linear Probe. http://www.idata8.com/rpackage/FeatureHashing/hashed.model.matrix.html
