The tensile properties of the lightweight titanium-based carbon-fibre/epoxy laminates (TI-CF FMLs) were investigated under quasi-static loading. A comprehensive experimental study was conducted for eleven different types TI-CF FMLs (considering various metal sheet thicknesses, volume fractions and fibre orientations) as well their associated constituent materials (i.e., Ti-6Al-4V laminates). Specimens fabricated using vacuum bagging technique in an autoclave. Theoretical predictions fraction...
This study investigated the low-velocity impact response of titanium-based carbon-fibre/epoxy laminate (TI-CF FML). A comprehensive experimental was carried out with energies ranging from 16.9 J to 91.9 J. Finite element analysis, performed using ABAQUS, employed elucidate failure mechanisms laminate. Three distinct damage modes were identified based on energy levels. The absorption characteristics TI-CF FML analysed, revealing that maximum is achieved and remains constant after penetration...
Spring-connected lumped mass models are well-known tools for simulating the impact actions including forces generated at point of contact which responsible localized damage to target. However, stiffness properties impactor would need be known in order that such can simulated with good accuracies. For most projectile materials, information required modeling is not available. A computational algorithm forms part a new technique introduced this paper. Cricket ball was used as example illustrate...
Expressions for determining the value of impact force as reported in literature and incorporated into code provisions are essentially quasi-static forces emulating deflection. Quasi-static not to be confused with contact which is generated vicinity point between impactor target, responsible damage featuring perforation denting. The distinction two types context actions widely understood few guidelines have been developed their estimation. can many times higher than that lasts a matter...
The contact stiffness of a mechanical bonding surface is an important parameter in determining the normal and radial force. To improve calculation accuracy force model, roughness energy loss that necessarily occurs during impact process should be considered comprehensively. study revolute joint with clearance more accurately case dry friction, nonlinear coefficient model considering was established based on fractal theory, which considers elastic, elastic-plastic, plastic deformations...
Certain types of damage generated by the impact a solid object are correlated with amount force that is localized around area contact between impactor and surface target. The stiffer impactor, higher when impulse delivered held constant. Thus, realistic simulations finite element analysis (FEA) require representative, detailed, information dynamic compressive properties both In situations where relevant material have not been documented, estimation filled uncertainties. addressing this...
This study presents a generic model for constructing shear-wave velocity (VS) profiles various conditions that can be used modeling the upper-crustal modification effects in ground motion simulations seismic hazard analysis. The piecewise P-wave (VP) profiling is adopted first place, and VS profile obtained by combining VP VS/VP model. constructed from field measurements, experimental data, or CRUST1.0 data collected worldwide. By making best use of regionally/locally geological information,...
The clearance of the revolute joint influences accuracy dynamic parameter identification. In order to address this problem, a method for identification an X–Y pointing mechanism while considering is proposed in paper. Firstly, nonlinear model was established based on modified contact model, which took effect asperity surface into consideration. Secondly, with aim achieving anti-interference incentive trajectory, trajectory optimized according condition number observation matrix and driving...
