Analysis of compression strength of corrugated shipping containers with different designed hand holes

The purpose of this study was to examine the compression strength of the corrugated shipping containers having the conventional purpose hand holes and the arc top hand holes. Generally, the arc top hand hole has stronger tear strength than the conventional purpose hand hole, but the arc top hand hole has a larger opening area than the conventional purpose hand hole, and the larger opening area needs more space of a dispersion of compression stress to increase compression resistance. However, when a hand hole has enough space to distribute compression stress, the only one variable is the width of the opening area in shipping containers if the containers have the same dimensions. In this study, two designs of the hand hole have the same width of opening area and are located to have enough space to distribute compression stress. As a result, the resistance forces of containers are the same in each different environment
