1. Introduction
Sugarcane harvesting involves cutting of the plant stalks at ground level. Traditional harvesting of sugarcane is done manually using hand cutters, which is quite laborious, time-consuming and expensive (Emerson, 2007). Burning the field before harvest is a common practice to make sugarcane cutting simpler and more efficient (Sangla and Suppadit, 2005). However, burning also contributes to gas and smoke emissions, which could be hazardous to human health and the environment (global warming), as well as causing soil and sugarcane deterioration (Eggleston et al., 2008; Ribeiro, 2008). To simplify the harvesting process and to cope with the diminishing supply and increasing cost of labor, mechanical harvesters/cutters were developed (Iwai and Emerson, 2008). Harvesting of sugarcane involves cutting at the internode of the base stalk. The sugarcane stalk is divided into nodes and internodes, with the internodes being the softer part (Persson, 1987). Chopper harvesters, which utilize rotary blade cutters have been reported to not only maximize the quantity and quality of sugarcane production (Norris et al., 1998) but also to greatly reduce the burnt sugarcane labor requirements (Eggleston et al., 2008) and hasten the harvesting process (Iwai and Emerson, 2008). To develop or design an appropriate mechanical sugarcane cutter, the physical and mechanical properties of sugarcane need to be taken into consideration. Yangyuen and Wongpichet (2006) reported that physical properties such as the cane length, stalk diameter, static friction coefficient between the sugarcane and mild steel surfaces, cross-sectional area and density are important in designing cane cutters. Moreover, data on the mechanical properties such as stressestrain curve, Young's modulus, toughness, modulus of rupture, energy of rupture, energy of fracture, hardness, shear strength, compressive strength and Poisson's ratio, which can be obtained through static or impact tests, are also required (Chang et al., 1982). All the above-mentioned properties though, depend on the plant species, variety, stalk diameter, maturity, moisture content, cellular structure, plant height, stalk-cutting direction and bending-plant knockdown (Shinners et al., 1987).
