Abstract

Studying the mechanical behaviour of oil palm fruitlet could be helpful in oil palm grading operation. This work investigates the mechanical behaviour of oil palm fruitlet by using finite element method. An axisymmetric model of a single oil palm fruitlet was developed to simulate the pin puncture test, drop test and compression test. The parameters were varied to investigate their effect on the stress-displacement curve. The stress relaxation test results showed the evidence of the viscoelastic behaviour of the oil palm mesocarp. A parametric study of the mesocarp-kernel interface properties was also carried out. The results showed that the model is not sensitive to the varying parameters due to the boundary conditions that limited the movement of the fruitlet. The model has potential in fruit maturity detection application.
