The state of abrasion of blade edge and the stress distribution in Japanese-Hoe was examined by using photo-elasticity photograph
The results were as follows;
1) Abrasion volume of the blade edge of Japanese-Hoe was larger than the other parts, especially in right side. The fact that abrasion volume is not symmetrical on both side is due to the manners it is used, and the edge of right side is necessary to be reinforced.
2) The stress in Japanese-Hoe concentrates on a part of ETSUBO (handle hole in Japanese-Hoe) and the both sides of blade edge. When horizontalforce acts on it. The shearing stress in the both sides of blade edge was 2.1 times as large as the stress in ETSUBO.
3) The stress in Japanese-Hoe concentrates on a part of ETSUBO when verticalforce acts on it. In this case the shearing stress was 85 times as large as that when horizontal-force acts.
