2020年5月1日 · Failure modes in lap joints with or without the filler material under the tensile shear testing condition may include the interfacial shear fracture, the nearly normal fracture in the plate materials, and necking in various locations.

2024年6月20日 · To understand adhesive performance, it is essential to consider how applied force and test conditions affect lap shear strength. Certain failures modes can be achieved by varying the way in which force is exerted onto a specimen whereas the rate of applying loads can influence the measured shear strength.

Different necking conditions are considered as precursors to the two failure modes in the no-damage model. It is found out that a small ratio of spot diameter to plate thickness promotes interfacial shear failure while a large ratio favors plug failure.

2021年11月24日 · Failure modes of lap-joint are analyzed on fractured surfaces and confirmed by finite element simulation in which the cohesive failure mode mainly occurs with the highest distributed...

2024年12月30日 · Mao and Hu 18,19 found, the ultimate failure load of composite laminate single-lap adhesive joints increases with the increase of lap length and tends to a stable value, the lap shear...

The fatigue failure modes of FDS joints in lap-shear speci - mens of dissimilar sheets of aluminum, magnesium, and steel sheets are discussed and presented in Scholz et al. [6].

2015年6月1日 · In this paper, the failure modes and fatigue behaviors of ultrasonic spot welded, adhesive-bonded, and weld-bonded lap-shear specimens of dissimilar magnesium AZ31B-H24 sheets and galvanized mild steel sheets are examined.

2012年9月1日 · The failure modes depend on the edge effects described by the ratios H/D and W/D: the decrease of the ratio H/D promotes the shear-out failure mode; the decrease in the ratio W/D promotes the net-tension failure or the mixed failure modes (tension-shear).

2016年9月6日 · This research focuses on investigating the different mechanisms that lead to a failure in FSBR joints under lap-shear tensile tests.

2024年10月1日 · SEM observations of the bonded joint sections revealed that the primary failure modes were adherend failure and adhesive layer failure. Finite element simulations indicated that fiber...
