Reduced finite element square techniques (RFE2): towards industrial multiscale fe software [PDF]

, 2019
Reduced order modeling techniques proposed by the authors are assessed for an industrial case study of a 3D reinforced composite laminate. Essentially, the main dominant strain micro-structural modes are obtained through standard reduced order modeling ...

Evolution law of the activation and energy storage of fault with hard rock bridge under mining influence

Meitan xuebao
The presence of slide-resistant structures within faults alters the laws of energy accumulation and slip behavior, resulting in significant differences in the mechanisms of fault activation and instability compared to conventional understanding. To study

Recent crustal movement and great earthquakes in Qinghai-Tibet sub-plate

Geodesy and Geodynamics, 2011
Crustal movement and incremental-movement data observed repeatedly at GPS stations during 1999–2009 were analyzed to study the effect of two earthquakes of Ms8.1 and Ms8.0 that occurred in 2001 and 2008, respectively, in Qinghai-Tibet sub-plate and its ...

Physical and Mechanical Characterization of Several Varieties of Oil Palm Mesocarp Fibers Using Different Cross-Sectional Assumptions

Journal of Natural Fibers, 2021
This study focuses on the characterization of plant fibers. Pressed Oil Palm Mesocarp Fibers (OPMFs) coming from different varieties (Dura, Tenera, and Pissifera) are subjected to a unitary tensile test.

Measurement of the direct energy gap of coherently strained Sn_xGe_(1–x)/Ge(001) heterostructures [PDF]

, 2000
The direct energy gap has been measured for coherently strained Sn_xGe_(1–x) alloys on Ge(001) substrates with 0.035 < x < 0.115 and film thickness 50–200 nm. The energy gap determined from infrared transmittance data for coherently strained Sn_xGe_(1–x)

Landau levels in deformed bilayer graphene at low magnetic fields

, 2011
We review the effect of uniaxial strain on the low-energy electronic dispersion and Landau level structure of bilayer graphene. Based on the tight-binding approach, we derive a strain-induced term in the low-energy Hamiltonian and show how strain affects
