由利兹大学和达勒姆大学联合进行的研究，对轴向加强棱柱体在纯拉伸下的行为进行了研究，得出了预测此类构件变形的公式，该公式取决于任何特定载荷下的裂纹间距。这是一个问题，似乎没有在过去的研究显着，本文介绍了裂纹间距的发展调查。这已经通过开发裂纹形成过程的随机模型来完成。这些模型允许考虑各种可能的假设，并确定最现实的假设。随机建模的结果，然后被用来开发公式预测的变形，这已被测试对大量的实验数据。实验和计算结果之间的协议已被证明是好的。
Research carried out jointly by the University of Leeds and the University of Durham into the behaviour of axially reinforced prisms subjected to pure tension led to formulae for the prediction of the deformations of such members that depended on the crack spacing under any particular load. This is a subject that does not appear to have been studied significantly in the past, and this paper describes an investigation of the development of crack spacing. This has been done by developing stochastic models of the process of crack formation. These models permitted various possible assumptions to be considered and the most realistic identified. The results of the stochastic modelling have then been used to develop formulae for the prediction of deformations, which have been tested against a large body of experimental data. Agreement between the experimental and calculated results has been shown to be good.
