A Method to Measure Young’s Modulus and Yield Stress of Raw Paper
摘要
Abstract
Young’s modulus and yield stress of raw paper are necessary performance indicators as they provide the essential foundation for subsequent analyzing processes of the mechanical behavior of paper, therefore, determination of these two indicators objectively and accurately are critical. Based on the existing defects in measuring Young’s modulus in previous studies, differentiation interval variation method was introduced to determine Young’s modulus and yield stress of raw paper to substitute traditional methods. Taking the corrugated paper with basic weight of 105 g/m2 for example, differentiation interval variation method was adopted, and the Young’s modulus of this paper was calculated as 2.51 GPa, while the yield stress was 5.11 MPa. Differentiation interval variation method could determine the end point of the linear elastic stage in stress-strain curve more objectively, which was the key point of calculating the Young’s modulus and yield stress of raw paper. By using this method, the Young’s modulus and yield stress of raw paper could be obtained with convenience and accuracy.关键词
