Load displacement curves and deformation patterns are compared with the experiments The proposed honeycomb/tube system is found to produce higher energy absorption capacities for both per unit mass and volume compared to an ordinary superposition of the constituents Almost a perfect crushing load plateau is achieved without a peak force
Axial crushing of tubes with multiple patterns of cut outs is studied using numerical analysis Commercially available finite element ABAQUS/Explicit® package is used to simulate the model under impact loading condition Split Hopkinson Pressure Bar SHPB is modelled to dynamically test the tube specimens with and without cut outs

Although specimen EF possesses the largest SEA 1094 J/kg under dynamic loading its crushing stroke is also of the greatest magnitude This indicates that its SEA has less lifting space than other configurations In contrast the SEA of specimen HT F is the lowest under the impact loading while its crushing stroke is also the smallest
The mean crushing load and wavelength of multi cell tube were investigated in this paper Numerical simulation was carried out firstly and the numerical values of mean crushing loads were employed to validate two existing theories The numerical wavelengths of walls in multi cell tube were compared with natural wavelengths and good agreement
In addition the external load on the sample to make power in the process of energy gathering and release is the granules particles compaction crushing of the internal driving force [15] it is necessary to explore the rock compaction crushing mechanical parameters on the basis of the analysis of its energy dissipation characteristics the
Understanding the crushing behaviour of honeycombs under dynamic loading is useful for crash simulations of vehicles and for design of impacting energy absorbers Available experimental techniques however are not always able to provide satisfactory precision for tests on honeycombs under impact loading
Crushing Response of Al 7005 and 7075 Tubes against Transverse Mechanics of Solids IF Pub Date 2024 11 01 DOI /s0025654424604518 Swapnil Shahane Gaurav Tiwari Nikhil Andraskar Abstract This paper addresses the energy absorption
Another loading case of tubes is the oblique loading Similar to the crushing behavior of tube under axial loading the obliquely loaded tubes also have great crushing length and high specific energy absorption per unit mass However this just happens in case of small load angle 5° 15°
Reddy and Al Hassani focused on crushing behaviour of composite sections including steel tubes and wood core [8] Different deformation modes higher axial load and energy absorption were achieved Load displacement curves of FE models and the tested specimens are plotted for ten specimens in Fig 16 The overall shape of the curves
This investigation aims to explore the crushing behavior and cumulative deformation of slag under cyclic loading by both cyclic triaxial simulation tests through 3D and in situ vibration tests The particle crushing index K g was proposed to characterize the evolution of particle crushing of slag The negative exponential Mechanics Empirical model M
In order to determine the crushing load in the Riera formula based on the material testing machine and the Hopkinson pressure bar experimental system the static and dynamic crushing behaviors of aluminum alloy under axial quasi static and different velocity impact loading were studied The load time curves of various sizes and shapes of aluminum alloy in static and
A LECA particle can be crushed into two parts three parts or multi parts more than three parts Local crushing at the loading point was occasionally observed; such local crushing could be dominant when the loading point happened to be located at or near a large internal pore which could be another source of particle strength variability

Different failure modes were observed in the dynamic crushing tests where progressive end crushing led to the highest SEA The peak load and SEA also increased with thickness while the SEA was insensitive to tubal length McGregor et al [10] compared the axial crushing of braided composited tubes at quasi static and dynamic rates
Theoretical analysis and numerical simulation methods were used to study the in plane crushing behavior of single cell structures and regular and composite honeycombs Square hexagonal and circular honeycombs were selected as honeycomb layers to establish composite honeycomb models in the form of composite structures and realize the
