This mixed-mode bending (MMB) test was analyzed using both finite-element procedures and beam theory to calculate the mode I and mode II components of strain-energy release rate GI and GII, …

When applied to adhesive joints, the MMB test appears to work well for brittle adhesives while large samples are required to avoid plastic deformation of the adherends in more ductile joints.

Dec 11, 2022 · 1.1 This test method covers the determination of interlami-nar fracture toughness, Gc, of continuous fiber-reinforced composite materials at various Mode I to Mode II loading ratios using the …

Aug 25, 2009 · The MMB test fixture is gaining popularity and is, today, the preferred method for quantifying the mixed-mode fracture toughness of composites, particularly now that ASTM D 6671 is …

The Mixed-Mode Bending test apparatus is used to split the laminate specimens to determine the delamination of fracture toughness. The test specimen is a rectangular, unidirectional laminated …

Jan 4, 2013 · The MMB test can be regarded as the superposition of pure mode I and mode II tests, namely, the double cantilever beam (DCB) and end-notched flexure (ENF) tests, respectively [6]. …

Aug 1, 2021 · In this investigation, a secondary bonded laminate composed of uni-directional (UD) pultrusion carbon fiber reinforced polymer (CFRP) composite plies is tested in order to determine its …

Oct 1, 2003 · The mixed-mode bending (MMB) test for delamination toughness was first introduced in 1988. This simple test is a combination of the standard Mode I (opening) test and a Model II (sliding) …

Sep 1, 2000 · The mixed-mode bending (MMB) test for delamination toughness was first introduced in 1988. This simple test is a combination of the standard Mode I (opening) test and a Mode II (sliding) …

The paper presents a mechanical model of the mixed-mode bending (MMB) test used to assess the mixed-mode interlaminar fracture toughness of composite laminates.
