Dynamic Nonlinear and Residual Deformation Behaviors of the Fly Ash-Modified Loess

Shock and Vibration, 2021
Metastable loess soils can deform, inducing geological and engineering disasters. Therefore, the behavior of the loess under dynamic load is gaining massive attention from researchers to improve the strength of the soils.

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

Advanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Discussions on elastic parameters of soil for land subsidence caused by decompression of confined aquifer in deep excavation

Yantu gongcheng xuebao, 2017
The relationships among the soil shear modulusobtained by oedometer tests, by pumping tests and the initial shear modulusof hardening soil small (HSS) model for soft soil under sensitive circumstance in Shanghai and Tianjin are studied. The HSS model is

Temperature-Dependent Model for Small-Strain Shear Modulus of Unsaturated Soils [PDF]

Journal of Geotechnical and Geoenvironmental Engineering, 2020
AbstractNear-surface soils in geotechnical and geoenvironmental applications are often unsaturated, and natural or imposed changes in temperature may lead to a softening effect at constant suction ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Constitutive behavior of Port-Said Clay under seismic and small strain static conditions

Ain Shams Engineering Journal, 2018
Port-Said Clay is very soft to firm clay deposited in the delta of an old tributary of the Nile at the east of Port-Said, Egypt. Despite the detailed characterization carried out for Port-Said Clay, no tests were carried out to measure its seismic or ...

Direct measurement of shear modulus at low frequencies and small strains

Journal of Physics: Conference Series, 2009
In many applications, one needs to measure elastic moduli of materials at low frequencies and small strains. With most techniques, such as ultrasonic pulse transmission or acoustic resonance, measurements are limited to a few discrete frequencies. These sound speed measurements are also indirect, since they involve density as well as elastic constants.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.
