Achieving large plasticity in bulk magnesium single crystal via dynamic compression

Journal of Materials Research and Technology
Compression tests were performed on magnesium (Mg) single crystals along the c-axis at ambient temperature. The plastic behaviors under quasi-static and dynamic conditions were comparatively analyzed. Twinning dominated quasi-static compression, in which

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales

Advanced Engineering Materials, EarlyView.
Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.

Towards better understanding of the strain–stress curve of cork: A structure–mechanical properties approach

Materials & Design, 2023
If the compressive strain–stress curve of cork has already been largely described, its relationship with the cork structure still requires a better understanding.

Mode Jumping of an Isogrid Panel Under Quasi-static Compression [PDF]

44th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2003
A wide column test of a composite isogrid panel subjected to quasi-static, axial compression is modeled with a hybrid-static dynamic computational method. The data from the test panel exhibited discontinuous responses in the compressive load for slowly increased end-shortening.

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

Advanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

Patterns of the Mechanisms of Deformation and Strain Hardening of Titanium Alloys and Metal Matrix Composites Based on the Analysis of Experimental Results on Quasi-Static and Dynamic Compressions

Успехи физики металлов
The deformation behaviour of titanium-based alloys and their composites during quasi-static and high-strain-rate compressions is analysed based on the earlier method developed by V.F.

Dynamic and quasi-static lateral compression tests of ceramics tubes [PDF]

Le Journal de Physique IV, 1994
In order to investigate the deformation of ceramics tube in lateral compression, a series of experiments was carried out at dynamic and static rates. It was observed that the load and deflection when fracture occurred in dynamic tests were greater than those obtained in static tests. However, a difference between Young's moduli obtained dynamically and

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.
