WebMay 1, 2024 · 2.3.1. 3-point bending A 242E Artemis DMA (Netzsch, Germany) was used to perform the 3-point bending tests. Tests were performed at a frequency of 1 Hz (as recommended by ASTM D5023-07 and ASTM E1640-18 and often used in literature) and an amplitude of 40 μm with a force limited to 10 N. WebA three-point bend fixture is used for ASTM D790. This fixture consists of a loading nose attached to the moving crosshead and a fixed member with two specimen supports, or anvils, which can be adjusted to fit the distance of the specimens' support span.
