WebSep 16, 2024 · 3-point bending. In the study, these properties are determined using a NETZSCH DMA 242E Artemis in 3-point bending mode. This mode is the most common test method, because it puts the sample under a combined compression-tension load and therefore, provides the tensile moduli E’ and E” as well as the damping factor tanδ as … Web(0.121%). If the DMA is used in the 3-point bending mode and the force equivalent to 455 Pa is applied on a sample, then the temperature at which the DMA sample deflects by 0.121% strain is the DTUL. The DTUL is a single-point measurement. The effect of certain molecular characteristics such as crystallinity and cross-linking affect the DTUL (1).
