“…Since the shaper would deform plastically, due to the impact of bullet, a plastic model should be considered in addition to the elastic model in the material model of the shaper. The plastic model selected for the 2024 aluminum alloy was a Johnson-Cook model developed in literature [19]. The dimensional settings of the components in numerical simulations were also consistent with the settings in experiments.…”

At the current stage, there is an urgent need for new techniques to dynamically calibrate advanced wide-range (up to 104 N~105 N) triaxial force transducers. Based on this background, this paper proposes a novel impact calibration method, specifically for the triaxial force transducer, with a wide range and high-frequency response. In this method, the Hopkinson bar, which is typically used to test the dynamic mechanical properties of materials, was used as a generator to generate reference input force for the transducer. In addition, unlike conventional methods, the transverse sensitivities of the transducer were given necessary importance in the proposed method. The calibration result of the triaxial force transducer was expressed in a sensitivity matrix, containing three main sensitivity coefficients and six transverse sensitivity coefficients. The least squares method (LSM) was used to fit the sensitivity matrix linearly. Calibration experiments were performed on a typical triaxial force transducer. Several key issues, involving the validity and the test range, of the method were further investigated numerically. The feasibility and validity of the method were eventually confirmed. The test range of the method can be up to 106 N.

“…The current research on the impact penetration problem still mainly concerns target plate failure and ballistic limiting velocity involved in different head shape projectiles hitting different types and thicknesses of targets vertically or inclined, and the velocity problem involved in low-velocity impact and anchored and embedded targets is less studied. Campbell et al [ 8 ] analyzed the effect of mesh sensitivity on ballistic terminal velocity by comparing the ballistic terminal velocity problem of flat-headed and ogive harpoons impacting aluminum honeycomb panels through simulation and experiment; Dudziak et al [ 9 ] studied the change in ballistic limiting velocity of blunt projectiles and conical projectiles impacting 3 mm steel plates, and they analyzed the cracking pattern of steel plates at low temperatures; Aglietti et al [ 10 ] analyzed the velocity and the impact of harpoons during harpoon impact experiments on aluminum honeycomb panels in the RemoveDEBRIS project; Fras et al [ 11 ], Wang et al [ 12 ], Kpenyigba et al [ 13 ], and Deng et al [ 14 ] studied the ballistic terminal velocities and the target failure forms of three structures with blunt projectile, hemispherical projectile and ogival projectile impacting high-strength armor steel, 2024-T351 aluminium alloy plate, mild steel sheets, and 6061-T651 aluminium alloy thin plates by conducting simulations and experiments; Rusinek [ 15 ] analyzed the effect of bullet diameter on the ballistic terminal velocity under the same initial kinetic energy and the failure form of the target plate.…”

The space harpoon is a rigid-flexible, coupled debris capture method with a simple, reliable structure and a high adaptability to the target. For the process of impacting and embedding the harpoon into the target plate, the effect of friction at a low-velocity impact is studied, and the criteria for effective embedding of the harpoon and the corresponding launch velocity are determined. A simulation model of the dynamics of the harpoon and the target plate considering tangential friction is established, and the reliability of the numerical simulation model is verified by comparing the impact test, focusing on the kinetic energy change and embedding length during the impact of the harpoon. The results show that the frictional effect in the low-velocity impact is more obvious for the kinetic energy consumption of the harpoon itself, and the effective embedding of the harpoon into the anchored target ranges from 50~90 mm, corresponding to a theoretical launch initial velocity between 88.4~92.5 m/s.

“…They also established Arrhenius and improved Johnson–Cook constitutive models to describe the dynamic mechanical behavior of the material at high strain rates and high temperatures. Bora et al [ 25 ] and Wang et al [ 26 ] introduced different expressions of Lode strain parameters into the Johnson–Cook failure model to characterize the dynamic failure behavior of materials. Wang et al [ 27 ] measured a high-temperature constitutive model of a TC4 titanium alloy sheet and found that both the strain-compensated Arrhenius model and the modified J–C model showed good prediction accuracy.…”

TC4 titanium alloy has excellent comprehensive properties. Due to its light weight, high specific strength, and good corrosion resistance, it is widely used in aerospace, military defense, and other fields. Given that titanium alloy components are often fractured by impact loads during service, studying the fracture behavior and damage mechanism of TC4 titanium alloy is of great significance. In this study, the Johnson–Cook failure model parameters of TC4 titanium alloy were obtained via tensile tests at room temperature. The mechanical behavior of TC4 titanium alloy during the tensile process was determined by simulating the sheet tensile process with the finite element software ABAQUS. The macroscopic and microscopic morphologies of tensile fracture were analyzed to study the deformation mechanism of the TC4 titanium alloy sheet. The results provide a theoretical basis for predicting the fracture behavior of TC4 titanium alloy under tensile stress.
