Abstract
Rubber stress relaxation behaviour is important to be studied and to be evaluated because it deals with the properties and function of rubber under stress condition. There are several methods that can be used to study rubber stress relaxation behaviour such as conventional tensile test and compression test. However, the surface deformation pattern and movement cannot be evaluated using these methods. The objective of this research is to develop a new method using scanner-based Digital Image Correlation (DIC) to evaluate the effect of various percentages of Bentonite loading in natural rubber on the physical stress relaxation behaviour. A flatbed scanner was used for the image acquisition. A motorized test rig was used to carry out the stress relaxation tests. Randomness test MATLAB algorithm was developed to investigate the randomness of speckles created on rubber specimen using different subset sizes. Scaling factor was determined at 0.042333
