Summary: This paper investigates the impact of residual stresses on the outcomes of an indentation plastometry technique using large spherical indenters. It is found that residual stress levels may influence the results, but the overall sensitivity is low, leading to relatively accurate inferred stress-strain curves.

Summary: This work aims to develop a viscoelastic formulation for the time-dependent finite deformation analysis of beams made of HMSMs under magnetic loading. The formulation is developed based on basic kinematic quantities and can be used for various geometries. The consistent fourth-order tangent tensors are presented for 3D bodies and beams made of HMSMs. A finite element formulation is developed for the numerical solution of beam problems. Several numerical examples are provided to demonstrate the applicability of the formulation.

Summary: A new procedure for identifying the mechanical behavior of individual phases within a bi-material is presented. The influence of hard inclusions on the material properties is studied using nano-indentation tests and finite element models, and a representative volume element (RVE) is defined. This method can be used to predict the mechanical properties of macroscopic experiments.

Summary: This investigation focuses on the use of the profilometry-based indentation plastometry (PIP) methodology to study the stress-strain relationships of materials near fusion welds. The results show that the weldments exhibit isotropy, while the parent metal has slight anisotropy. The PIP method is highly sensitive in detecting such anisotropy and shows good agreement with conventional uniaxial testing. Additionally, the PIP methodology allows for exploring properties in the transition zone between weld and parent metal, revealing variations that are difficult to examine using traditional testing methods.

Summary: In this study, the mechanical behavior of gelatin hydrogels was examined through indentation tests using a biphasic poroviscoelastic (BPVE) material model and finite element analysis. The relaxed shear modulus was found to be an intrinsic material property for soft tissues and hydrogels, suitable for comparison with results obtained from other experiments.

Summary: Traditionally, the effect of sample size on indentation of asphalt bitumens has been neglected. Recent studies have shown that sample size correction factors obtained through finite element simulations can significantly impact the results. This paper presents correction factors for cylindrical geometry indentation, where the results from finite element simulations differed from analytical results due to volumetric effects. Additionally, the correction factors were validated by demonstrating similar results among different sample sizes after adjustment.

Summary: This article introduces the use of profilometry-based indentation plastometry (PIP) to obtain mechanical property information of particulate metal matrix composites (MMCs). By conducting PIP tests and conventional uniaxial tests on four different MMCs, it is demonstrated that reliable stress-strain curves can be obtained with PIP, although prenecking fracture is possible. The article also highlights the importance of considering scale effects and conducting repeat PIP tests to account for the scatter in PIP profiles and obtain macroscopic properties. Despite these challenges, PIP testing is shown to reliably detect the relatively minor macroscopic anisotropy exhibited by forged materials of this type.

Summary: The cervix is a vital mechanical barrier to protect the growing fetus and its remodeling is necessary for safe parturition. This study investigates the time-dependent behavior of the cervix under compressive states using a porous-viscoelastic material model and inverse finite element analysis. The results show that the porous-viscoelastic model captures the force-relaxation response of the cervix well and has the potential to understand premature cervical remodeling and interpret force readings from in-vivo measurement tools.

Summary: This study examines the effect of dispersed porosity in a metal on its plastic deformation. The results show that porosity reduces stress levels during yielding and work hardening, with the effect strength proportional to the pore content. There is no significant difference between tension and compression in the strength of the effect, although porosity does reduce tensile ductility.

Summary: This paper investigates the finite deformation and instabilities of viscoelastic soft magnetic soft materials (HMSM). A numerical model is developed to analyze the buckling and snap-through instabilities of two typical HMSM structures (i.e. beam and spherical shell) with viscoelastic effects. The results show that the viscoelastic effects delay the onset of instability and suppress the snap-back phenomenon. This study provides an effective numerical model for analyzing the finite deformation and instabilities of viscoelastic HMSM and may guide the design of HMSM devices.
