“…While the cRDCB specimen may exhibit less crack extension than the DCB specimens tested, there are many applications, such as low-velocity impacts [31][32][33] or fatigue damage initiation [5], where such extensive crack extension is not needed. Furthermore, the cRDCB has far greater sensitivity to and resolution of the early damage behaviors that dominate such applications.…”

BackgroundInterlaminar delamination is a common damage mechanism in composite laminates that can lead to structural failure. Assessment using contemporary numerical modeling techniques requires delamination behavior as a traction-separation response. However, existing experimental characterization approaches are not well suited to support these modeling techniques as specimens were developed to assess single delamination parameters, not a full traction-separation response, or utilize analysis schemes that require knowledge of material properties. ObjectiveTo develop a test specimen and data analysis methodology to directly measure the traction-separation response of Mode I delamination in a laminated fiber-reinforced polymer (FRP) composite, including strength, toughness, and damage response. 2 MethodsThe proposed composite Rigid Double Cantilever Beam (cRDCB) specimen is comprised of a [0]_4 unidirectional E-glass/epoxy laminate co-cured to rigid metallic adherends. Traction-separation response was assessed directly from measured force and displacement behavior using a closed-form analysis scheme that does not require a priori knowledge of composite material properties. Standard double cantilever beam (DCB) tests were performed for comparison. ResultsThe cRDCB specimen captured early damage initiation and progression in greater detail than the DCB, with measured strain energy release rates agreeing well between the two approaches. The cRDCB also captured the effects of large-scale damage mechanisms such as fiber bridging. The measured traction-separation responses are suitable for scenarios where prediction of the initiation and early damage response of delamination is important. ConclusionsCombined with a data processing technique, a single cRDCB test enabled measurement of the full Mode I tractionseparation response. In addition, the cRDCB provided high-resolution and could detect early-stage Mode I delamination damage in FRP laminates. The measured traction-separation responses can be directly inputted into cohesive zone models to predict the initiation and progression of Mode I delamination.

Nonpenetrating repeated impact effect to the damage behavior of prestressed glass/epoxy composite pipes

Glass-reinforced plastic (GRP) composite pipes, the use of which has been increasing rapidly in many areas in recent years, may be exposed to the impact of different objects during assembly, operation, repair, and maintenance. Since composite materials are sensitive to impacts, it is vital to examine damage to the material. In this study, the repeated impact response of GRP composite pipes under internal hydrostatic pressure was investigated. In order to simulate different operating conditions on the GRP samples, a prestress was created by applying 4, 16, and 32 bar internal hydrostatic pressure. Then, the prestressed pipes were subjected to low velocity repeated impact tests. As a result of repeated impact tests at low velocity, changes in maximum displacement amount, maximum contact force, energy absorption capacity, and impact velocity were evaluated depending on the number of impacts applied to the samples. The changes in the strength of the samples subjected to repeated impact tests at different internal pressure levels were determined by the hoop tensile tests performed according to the ASTM D2290 standard. As a result of the hoop tensile tests, the variation of the material's tangential tensile strength and damage behavior according to impacts' number and the prestress were investigated.

“…Hu et al [10] investigated the effect of kevlar fiber on impact strength by performing low velocity impact tests on carbon fiber reinforced polymer composites hardened with short kevlar fibers. Zhang et al [11] conducted low velocity impact tests on steel-glass thermoplastic hybrid plates produced by direct injection molding process and examined the impact responses of the plates such as impact absorption energy, maximum load and damage area. Liu et al [12] compared the impact strengths of unidirectional-woven hybrid composites and pure unidirectional carbon fiber reinforced composites at different energy levels under the same boundary conditions.…”

In this study, the impact behavior of patch-repaired layered composite plates was numerically investigated under low velocity impact loads. For this purpose, composite plates designed in different geometric combinations were repaired with patches using various adhesives. Impact behavior of these composites investigated by dropping the strikers with different velocities on the repaired composite plate. The laminated composite was used as the sheet and patch material, and the orientation angles were set as [0°/45°/45°/0°] for the sheet and [0°/45°] for the patch. ANSYS-Ls-Dyna finite element packet program was used for threedimensional modelling and solution. It was determined that the hexagonal patch type performs better than other patch geometries.
