Coulomb plasticity within the fault zone

Geophysical Research Letters, 1992
We represent a well‐developed fault by a layer of granular material (fault gouge) confined between two competent fault blocks. Slip on such a fault involves plastic shearing of the fault gouge. That is, the fault gouge behaves as a Coulomb material, and the plastic flow is accomplished by slip on the two sets of Coulomb shears appropriate to the stress

High‐Entropy Alloy Interlayers Toward Advanced Joining for High‐Performance Structural Applications: Current Progress and Emerging Challenges

Advanced Engineering Materials, EarlyView.
HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...

A Novel Approach to Estimate the Transition Temperature via Dynamic Nanoindentation

Advanced Engineering Materials, EarlyView.
A new dynamic nanoindentation‐based method was developed that uses the stiffness ratio as an indicator of the elastic–plastic deformation contributions at different temperatures. The approach successfully identified transition temperatures in ferritic steel and distinguished them from continuously ductile austenitic steel.

Plastic Deformation Zone in Electromagnetic Cutting [PDF]

Archives of Metallurgy and Materials, 2017
AbstractThis paper presents the application of the electromagnetic field as a tool for metal sheet cutting. The experiments showed that one can easily adapt the conventional cutting equipment to the electromagnetic cutting technology and thereby eliminate the mechanical work of the punch and the press.

FastNano Liquid: An Automated Platform for Small‐Angle X‐ray Scattering‐Based Materials Discovery

Advanced Engineering Materials, EarlyView.
We present FastNano Liquid, an automated small‐ and wide‐angle X‐ray scattering platform for the combined synthesis and characterization of (nano)materials. The platform is coupled to varied reactor workflows for both in situ studies of reaction kinetics and ex situ screening of synthesis conditions to support machine learning‐guided exploration ...

Effect of Cu and CuP Additions on the Microstructure and Nanoindentation‐Based Fracture Behavior of CoNiAlSi Ferromagnetic Shape Memory Alloys

Advanced Engineering Materials, EarlyView.
Cu and combined Cu–P microalloying refine the microstructure and enhance the nanoindentation‐derived fracture resistance of CoNiAlSi ferromagnetic shape memory alloys without suppressing the martensitic transformation. Comparative SEM, DSC, and nanoindentation results reveal that the CuP‐containing alloy provides the most balanced response, achieving ...

Experimental Study on the Butterfly Shape of the Plastic Zone around a Hole near Rock Failure

Fractal and Fractional
The precursor of rock failure around a hole has always been one of the research hotspots in the field of rock mechanics, and the distribution of the plastic zone is often adopted to reflect the location and form of rock failure.

Plastic Zone Development During Embankment Construction

Soils and Foundations, 1977
ABSTRACT Rapid stage construction of homogeneous and isotropic embankments is examined. The finite element model constructed assumes an undrained, linearly elastic-perfectly plastic behaviour of the soil. The von-Mises criterion is used to identify when the shear strength is exceeded. The plastic range analysis is based on Yamada et al.

Tight Hammering for Plastic Zone of Materials

IOP Conference Series: Materials Science and Engineering, 2019
Considering the failure due to cracks and peeling from curved surfaces of complex components, we used the tight hammering method to study the internal plastic deformation zones of curved-surface Q235 steel specimens after hammering shock and display relevant information.
