“…82,83 An increase with increasing particle content found in the strain rate sensitivity parameter for post-yield strength signifies a higher resistance to localized deformation exhibited by biocomposites compared to neat ABS. 84 As discussed earlier, the strain softening is an indicator of the resistance to local plastic deformation imparted by a material. As known, strain softening plays a primary role in the onset of strain localization.…”

This study aimed at investigating the effects of hemp fiber particles with an approximate size of 500 μm added at three various weight ratios including 1wt%, 5wt%, and 10wt%, on the tensile behavior of Acrylonitrile-Butadiene-Styrene (ABS) at low strain rates varying from 1 × 10−4 to 6.25 ×10−2 s−1. Regardless of a strain rate, tensile test results revealed that increasing particle content leads to a significant improvement in the tensile modulus of neat ABS but a decrease in its post-yield strength. Additionally, it was found that the ductility of neat ABS decreases with both increasing particle content and strain rate. The results also showed that ABS experiences a less intrinsic yield drop after post-yield as both particle content and strain rate enhance. Additionally, it was concluded that increasing the weight ratio of particles in ABS leads to higher resistance to plastic localized deformation. Moreover, it was found that an improvement in the weight ratio of particles makes the post-yield strength of ABS more susceptible to strain rate but leads its tensile modulus to be less sensitive to strain rate. The tensile test results were found to be consistent with both X-ray diffraction (XRD) and Fourier Transform Infrared (FT-IR) Spectroscopy results.

“…Xiao et al [ 67 ] showed that the slopes of contact stiffness–depth curve, modulus, and hardness of cured isotropic conductive adhesive increase with the increasing loading strain rate. Mao et al [ 68 ] showed that the hardness and creep flow of the tripler plane of potassium dihydrogen phosphate crystal increase with the loading strain rate. Znemah et al [ 69 ] analyzed the effects of strain rate and testing temperature on the hardness of Inconel 718 manufactured by selective laser melting (SLM) and measured by nanoindentation.…”

This paper investigates the orientation-dependent characteristics of pure zinc under localized loading using nanoindentation experiments and crystal plasticity finite element (CPFEM) simulations. Nanoindentation experiments on different grain orientations exhibited distinct load–depth responses. Atomic force microscopy revealed two-fold unsymmetrical material pile-up patterns. Obtaining crystal plasticity model parameters usually requires time-consuming micromechanical tests. Inverse analysis using experimental and simulated loading–unloading nanoindentation curves of individual grains is commonly used, however the solution to the inverse identification problem is not necessarily unique. In this study, an approach is presented allowing the identification of CPFEM constitutive parameters from nanoindentation curves and residual topographies. The proposed approach combines the response surface methodology together with a genetic algorithm to determine an optimal set of parameters. The CPFEM simulations corroborate with measured nanoindentation curves and residual profiles and reveal the evolution of deformation activity underneath the indenter.

“…The specific nature of the anelastic behavior in KDP is not yet clear, but it has been mentioned in recent research. 18,26 Significant rebound deformation or elastic deformation can be observed as the cutting depth increases. The reversed or elastic deformation is significant, reaching up to 38.77% of the original deformation, and can be observed with increasing cutting depth.…”

Potassium dihydrogen phosphate (KDP) crystals are widely used in high-power laser systems and inertial confinement fusion applications. However, machining KDP crystals using ultra-precision fly-cutting technology poses challenges due to the combined elastic, plastic, and brittle deformation mechanisms, making it difficult to analyze the material removal process. This investigation aims to observe and analyze the elastoplastic behavior of KDP crystals in the ductile region, which has received limited attention in previous studies. Nanoindentation experiments were conducted to analyze the elasto-plastic transition in KDP crystals, employing an approach instead of the traditional Oliver-Pharr method. Additionally, a cutting experimental method was developed to observe the reverse behavior during manufacturing by introducing a process with a 0 nm depth of cut. The results reveal significant rebound deformation and anelastic behavior, providing a comprehensive understanding of the deformation mechanism in KDP crystals at the nano-and micro-scale cutting levels. This knowledge contributes to modifying the diamond turning process and optimizing the fabrication procedure of KDP crystals.
