Mechanical Behaviour of Rubber Seed under Compressive Loading

In this study, the mechanical behaviour of rubber seed was determined in terms of compressive force, stress, energy, deformation and elastic modulus at four levels of moisture content ranging from 9.1 to 14.8 % (w.b.), using the Universal Tensile Testing Machine, under compressive loading, with loading range (0-500 N), chart speed (50 rpm/mm) and cross head speed (1.5 mm/min) as testing conditions. The optimum peak values of force, stress, energy, deformation and elastic modulus at 14.8 % (w.b.) moisture content were 164.35±66.09 N, 2.09±0.59 N/mm2 , 0.27±0.07 Nm, 2.74±0.51 mm and 7.77±3.85 N/mm2 , respectively. Beyond elastic limit, the force of compression decreased quadratically with increase in deformation with high coefficient of determination (significant p
