Stress resultant plasticity for shells revisited [PDF]
, 2012 In this work, we revisit the stress resultant elastoplastic geometrically exact shell finite element formulation that is based on the Ilyushin–Shapiro two-surface yield function with isotropic and kinematic hardening.

Geofluids, 2022 The effect of geomechanics is crucial in the modeling of fractured reservoirs since fractures can be more stress-sensitive than the rock matrix. In fractured reservoirs, the microscale fractures are often homogenized into the matrix continuum leading to ...

An Effective Numerical Simulation Method for Steam Injection Assisted In Situ Recovery of Oil Shale
Energies, 2022 This paper presents an effective numerical simulation method for production prediction of in situ recovery of oil shale reservoirs with steam injection. In this method, finite volume-based discretization schemes of heat and mass transfer equations of the

Quasicontinuum simulation of fracture at the atomic scale [PDF]
, 1998 We study the problem of atomic scale fracture using the recently developed quasicontinuum method in which there is a systematic thinning of the atomic-level degrees of freedom in regions where they are not needed.

Imaging compaction band propagation in Diemelstadt sandstone using acoustic emission locations [PDF]
, 2008 We report results from a conventional triaxial test performed on a specimen of Diemelstadt sandstone under an effective confining pressure of 110 MPa; a value sufficient to induce compaction bands.

A phase-field method for modeling cracks with frictional contact
, 2019 We introduce a phase-field method for continuous modeling of cracks with frictional contacts. Compared with standard discrete methods for frictional contacts, the phase-field method has two attractive features: (1) it can represent arbitrary crack ...

Aging concrete structures: a review of mechanics and concepts [PDF]
, 2018 The safe and cost-efficient management of our built infrastructure is a challenging task considering the expected service life of at least 50 years. In spite of time-dependent changes in material properties, deterioration processes and changing demand by
