Comparison of Tangent Curve Method and Reciprocal Slope Transformation Method for Describing Mechanical Behaviour of Jatropha Curcas L. Bulk Seeds Under Compression Loading
Öz
The study investigates the use of two different methods for the description of
deformation characteristics of Jatropha curcas L. bulk seed in linear compression. These methods
include the tangent curve and reciprocal slope transformation. The merits and limitations of both
methods were also compared. The different methods were used for development of mathematical
equations for fitting experimental data describing the mechanical behaviour of Jatropha bulk seed.
Pressing vessel diameter 60 mm was used to compress the bulk Jatropha seed which was
measured at pressing height 80 mm. For tangent curve method, the experimental data was fitted
by using the Marquardt Levenberg process whiles the Least Square Method (LSM) satisfies the
reciprocal slope transformation method. Statistical analysis of both experimental and fitted data
coefficients of reciprocal slope transformation and tangent curve methods indicated significant
results with high coefficient of determination which suggests the suitability of both methods for the
description of deformation characteristic of Jatropha curcas L. bulk seed in linear compression.
