To obtain a more precise measure of the elastic modulus in tensile testing, utilizing advanced measurement techniques and high-precision instrumentation is essential. Employing a tensile testing machine with enhanced accuracy can significantly improve results. Additionally, increasing the number of specimens tested can provide a more reliable average value. Exploring different measuring apparatuses, such as digital extensometers or laser-based systems, can also yield better precision. Overall, a combination of improved equipment and methodologies is key to achieving more accurate measurements of elastic modulus.
