The main objective of the presented research was to find a model that describes the maximum compressive force of paper in its plane. The research began with crushing tests of a number of packaging paper samples of various lengths. It was shown that due to the specific structure of the paper and the high heterogeneity of its structure, packaging paper is material where it is difficult to determine the maximum compressive stress. Next, three analytical models describing the load capacity of a flat paper web were investigated and an alternative empirical model was proposed. The results of the performed tests are directly applicable in the calculation of the mechanical properties of corrugated cardboard and the determination of the load capacity of cardboard packaging.
本研究的主要目的是找到一个描述纸张在其平面内最大压缩力的模型。研究始于对多个不同长度包装纸样本的抗压测试。结果表明,由于纸张的特殊结构及其结构的高度不均匀性,包装纸是一种难以确定最大压缩应力的材料。接下来,研究了三种描述扁平纸幅承载能力的分析模型,并提出了一种替代的经验模型。所进行测试的结果可直接应用于瓦楞纸板力学性能的计算以及纸板包装承载能力的确定。
