Replication Data for: Survival analysis of tensile strength variation and simulated length-size effect along oak boards

Dataset used to develop and calibrate the model for localized tensile strength along oak boards. A survival (or censored) analysis is performed on the cell-wise tensile strength of boards, which delivers coefficients for two different candidate distributions: (i) Beta and (ii) 3-parameter Weibull distributions. For both distributions, a parametric and a regression analyses are made. The calibrated model is used to simulate tensile strength and modulus of elasticity (MOE) profiles along boards of different sizes. These virtual boards are then used to simulate the size effect of the studied boards. The localized tensile strength was obtained by first testing the board in tension until failure. The remnant pieces were then tested in tension again. This allowed to obtain between 1 and 4 tensile strength values per board. Since for the testing in tension a certain length has to be clamped, there are sectors of the board that cannot be tested, as they are within the clamped region. These regions are considered as censored data.

本数据集旨在开发和校准针对橡木板局部拉伸强度的模型。对单板细胞级拉伸强度进行生存分析（或称截尾分析），从而得出两种不同候选分布的系数：（i）贝塔分布和（ii）三参数韦伯分布。对于这两种分布，均进行了参数分析和回归分析。校准后的模型被用于模拟不同尺寸木板的拉伸强度和弹性模量（MOE）曲线。这些虚拟木板随后被用于模拟研究木板的尺寸效应。局部拉伸强度通过首先将木板拉伸至破坏，然后对残余部分再次进行拉伸测试而获得。这允许每块木板获得1至4个拉伸强度值。由于拉伸测试需要夹紧一定长度，因此木板的部分区域无法进行测试，因为这些区域位于夹紧区域内。这些区域被视为截尾数据。
