Numerical Investigation on Time-Dependent Deformation in Roadway
نویسندگان
چکیده
The roadway deformation normally relates to time especially for underground coal roadway. strength of soft is low, and therefore the increases gradually under constant stress with time, which called rheology deformation. In this study, based on a field case, rock mass properties data were obtained according test. A 3D numerical model was then established, rheological including horizontal vertical systematically analyzed. results showed that sidewall accounts almost 30% whole deformation, stable such around 60 days after excavation. tendency roof similar sidewalls, however, floor different. Then related suggestions maintaining stability proposed, useful in-field application.

Numerical Investigation of Circular Plates Deformation under Air Blast Wave
In the current research the maximum deflection of circular plates made of AA5010 and AA1100 alloys under blast load was investigated. Shock waves were produced by exploding a spherical charge in different distances from the center of plates. The ABAQUS software uses conwep equation for blast loading analysis. It was found the results of these simulations have about 30% to 40% inaccuracy in comp...
متن کاملNumerical solution of time-dependent foam drainage equation (FDE)
Reduced Differental Transform Method (RDTM), which is one of the useful and effective numerical method, is applied to solve nonlinear time-dependent Foam Drainage Equation (FDE) with different initial conditions. We compare our method with the famous Adomian Decomposition and Laplace Decomposition Methods. The obtained results demonstrated that RDTM is a powerful tool for solving nonlinear part...
متن کاملTime dependent transformations in deformation quantization
We study the action of time dependent canonical and coordinate transformations in phase space quantum mechanics. We extend the covariant formulation of the theory by providing a formalism that is fully invariant under both standard and time dependent coordinate transformations. This result considerably enlarges the set of possible phase space representations of quantum mechanics and makes it po...
