Two equations are presently used to relate folding endurance to the load on the test strip Neither of these contains the initial tensile strength of the paper as a term, though tensile strength greatly influences folding resistance. An equation is derived which relates initial tensile, load and ...
The tensile strength of paper can be modelled by a normal distribution with a mean of 240kPa and standard deviation 15kPa. What proportion of paper produced will have a tensile strength of less than 250kPa? What is the probability that the tensi...

The tensile strengths of paper from the test set, including both mechanical and kraft pulps, were well predicted by the two models. With this engineering approach, the strength characteristics of a pulp can be easily evaluated from fibre geometry, Z-strength, zero-span tensile strength and ...
The morphological characteristics of bogflows, bog bursts and other types of peat failures suggest that the tensile strength of peat may have had a significant influence on their occurrence and development. This paper describes a method for the determination of peat tensile strength utilising small bl...

Tensile strength is one of the most important mechanical properties of structural short fibre composites, and its prediction is essential for composite design. This paper develops a strength theory for three-dimensionally oriented short fibre-reinforced composites. The contribution of direct fibre strengthe...
