“…In this way, the incremental loop is continuous until the stress level reaches the appropriate value for each step to create impact damage. illustrates that the meshed view of the finite element model of high manganese steel plate is modeled by using eight node brick (C3D8R: Eight-node brick element with reduced integration) as linear elements and a semi-spherical impactor with a diameter of 20 mm is defined as four node (R3D4: 3D bilinear discrete rigid quadrilateral) elements [29]. The conditions determined in the experimental studies are also used in numeric model studies.…”

This work presents the results of experimental and finite element modeling studies of impact behavior on the response of a high content of manganese steel blanks with a 1.2 mm thickness of sheets, known also commercially as Hadfield steel (an austenitic structure with a basic composition containing C 1.2% and Mn 12%). The study was done with a standard drop weight test device under certain variable parameters (velocity: 3 m/s and 5 m/s and temperature: room temperature, 70 °C, 100 °C, and 140 °C). In this study, the evolution of force and energy values were analyzed depending on the time in the case of impact. Special care was given to the evolution of peak stress counters of finite element simulation for different temperatures. The results of the force-time, energy-time, and force-displacement curves under different temperatures and impact velocities are compared experimentally and numerically. Then the discussion are built on the effect of the operational parameters on the damage behavior of this steel. Both of these works (experimental and finite element modeling) were compared and highly satisfying results were obtained.

In the recent years a big focus is subjected to the response of structures subjected to out-of-plane loading such as blasts, impact, etc. not only to homogenous materials, but also to heterogeneous materials, such as composites. In the present study, low-velocity impact response of composite laminates was studied using ANSYS Workbench finite element code (FEM). The material of composite structure is orthotropic material reinforced by carbon fibers and have been taken from the Workbench material database. Plate consists of layers which are reinforced with unidirectional fibers in hexagonal and square array. Layer is considered as homogeneous transversely isotropic and layer stacking sequence is symmetrical or unsymmetrical.

“…Hashin‐based criterion has been successfully adopted by many researchers in the past to study and predict the behavior of many orthotropic or anisotropic materials; especially polymer composite laminate with either glass or carbon fiber reinforced. Despite being intensively used to simulate the strength of structures, Hashin‐based damage criterions have rarely been used for transversely isotropic natural fiber reinforced composites.…”

Experimental and numerical investigations of kenaf natural fiber reinforced composite subjected to impact loading

The aim of this work is to develop a Finite Element Model based on continuum damage mechanics to predict the structural response of Kenaf composite when subjected to high‐velocity impact. The stress–strain response of the Kenaf composite through the fiber direction was simulated to examine prediction accuracy of this simulation approach. A combined elastic‐damage material model, incorporating the 3D Hashin's failure criteria, was implemented into the ABAQUS/Explicit finite element code by user‐defined VUMAT material subroutines. The results from the model predictions were compared with experimental data obtained by SHPB compression testing. The developed Finite Element Model of the full‐scale test presented an accurate prediction of the strain waves in the bars and successfully replicated the structural impact response of Kenaf composite over the range of impact loadings studied. The model also provides a reasonably good agreement between numerical and experimental results on the effect of strain rate on the failure stress and failure strain. POLYM.
