What impact paramaters should used when comparing low velocity impact and quasi static indentation?
Best insight from top research papers
Quasi-static indentation testing can be used to assess the low-velocity impact behavior of composites by comparing the delamination damage threshold load and indentation depth. The quasi-static tests provide accurate predictions of impact damage resistance, but may underestimate the maximum load due to final fiber failure at higher energy levels. This is because the energy during quasi-static indentation is completely transformed or absorbed by the laminate, without considering factors such as vibration, heat, or inelastic behavior of the impactor or supports. Additionally, the strain rate effect may have a significant influence on fiber failure, but not on undamaged and delaminated damage.

What paramaters used to measure impact performance of composite under low velocity impact?\?5 answersParameters used to measure the impact performance of composites under low-velocity impact include impactor shape, impact energy levels, velocity of the impactor, stacking sequence, boundary conditions, geometry of the impactor, and impact angle. These parameters play a crucial role in determining the resistance and damage induced by low-velocity impacts on composite structures. Numerical simulations, finite element analysis, and experimental tests are commonly employed to assess the impact response of composite laminates. The Hashin failure criteria and Taylor's series expansion are utilized to model and predict the damage caused by low-velocity impacts, aiding in the design and enhancement of the structural integrity of composite materials.
What does time-force curve obtained from low velocity impact test refer to?5 answersThe time-force curve obtained from a low-velocity impact test provides crucial insights into the material behavior and failure characteristics under dynamic loading conditions. This curve showcases the relationship between the applied force and the duration of the impact, offering valuable data on the failure stresses, stiffness, and damage mechanisms. It helps in understanding the energy absorption capacity, ductility, and brittleness of the material when subjected to impact, aiding in the assessment of structural integrity and damage tolerance. Additionally, the curve aids in predicting the initiation and propagation of damage, such as delamination in composite materials, which may not be visually detectable but significantly impact the structural performance. The time-force curve is a fundamental tool in evaluating the response of materials to low-velocity impacts and guiding design considerations for structures exposed to dynamic loading.
What are the results of low velocity impact test?5 answersThe results of low-velocity impact tests on composite laminates varied based on the studies. In one study, the impact energy levels of 10, 15, and 20 J led to reductions of 18.1%, 28.7%, and 33.0% in compressive strength of carbon/epoxy composites. Another study focused on Glass Laminate Aluminium-Reinforced Epoxy (GLARE) laminates found that the laminate could sustain impacts up to 3.13 m/s, with delamination occurring at 3.49 m/s, and the maximum absorbed energy before failure was 14.43 J. Additionally, a comparison between a double-double (DD) laminate and a quadriaxial (Quad) laminate showed equivalent compressive strength and compression after impact (CAI) strength, with differences in impact damage morphology observed.
What are the exported results of low velocity impact test of GLAREs?5 answersThe low velocity impact tests of GLARE laminates have yielded several important results. The laminates can sustain impact velocities up to 3.13 m/s before delamination damage occurs, with a critical load beyond which delamination occurs at 3.49 m/s. The maximum absorbed energy by the laminate before catastrophic failure was found to be 14.43 J. Another study found that the first crack in the aluminum layer of GLARE laminates occurred at an impact energy of 18.5 J. The force-displacement response of GLARE laminates under concentrated quasi-static indentation force showed an obvious flat roof and instantaneous failure, different from CFRP laminates. The dissipated energy during low-velocity impact tests was found to be approximately equal to the impact energy. These results provide valuable insights into the damage resistance and energy absorption capabilities of GLARE laminates under low velocity impact conditions.
Does the static hardness (brinell or vickers) of functionally graded composites provide information on their impact resistance?5 answersThe static hardness of functionally graded composites can provide information on their impact resistance. The hardness, impact strength, and compressive properties of functionally graded nanocomposites (FGNCs) fabricated using 3D printing were found to increase with an increase in the wt. % of functionalized MWCNTs in high-density polyethylene (HDPE). Functionally graded ultra-high performance cementitious composite beams (FGCB) also showed superior flexural properties and impact resistance. Additionally, the fabrication of preceramic paper-derived functionally graded materials (FGMs) based on Ti3(Si,Al)C2 MAX phase resulted in materials with high flexural strength and anisotropic hardness. Furthermore, the processing and characterization of AA6061-TiB2 functionally graded metal matrix composites (FGMMCs) showed a variation in microhardness from the outer to inner region, indicating a potential correlation between hardness and wear resistance. Finally, the fabrication of Ti-Ni-C functionally graded composites using additive manufacturing showed an increase in hardness with the addition of Ni coated graphite.
How can I analyse the low velocity impact on structure?5 answersTo analyze low velocity impact on structures, finite element analysis can be used. This method allows for the determination of maximum energy absorption and damage modes in different types of sandwich structures. The impact resistance of the structure can be improved by modifying the design, such as changing the wall thickness distribution of the cores or moving the inner panel. Additionally, the type and thickness of the cores and facesheets, as well as interfacial reinforcement techniques, can influence the impact load and energy absorption of the sandwich structure. Delamination is a common type of impact damage in facesheets, and its behavior is dependent on the type of facesheet used. It is also important to consider the role of fluid structure interaction when analyzing low velocity impact on composite materials, especially in marine applications.
