报告题目:Estimating Stiffness of Rubber Plantation Timber: A comparative study the Smart Thumper Application and the Universal Testing Machine

报告摘要:
This study aimed to examine the accuracy of estimating the modulus of elasticity (MOE) of rubber plantation timber using both the SMART THUMPER™ application and the universal testing machine. The results indicated that there was no significant difference between the MOE values obtained from the two testing methods, as determined by a P-value of 2.06 (P>0.05). Specifically, the average MOE for the universal testing machine was calculated to be 10048±2610 MPa, while for the Smart Thumper App, it was 10155±2415 MPa. To further enhance the findings, it is recommended to conduct additional experiments involving groups of specimens with defects and clear specimens.
