Shockwaves in spillways with the particle finite element method
(Springer, 2020-01)
Article.
Accés obert
Article.
Accés obert
Changes in direction and cross section in supercritical hydraulic channels generate shockwaves which result in an increase in flow depth with regard to that for uniform regime. These disturbances are propagated downstream ...
Substrate design to minimize residual stresses in Directed Energy Deposition AM processes
(Elsevier, 2021-04)
Article.
Accés obert
Article.
Accés obert
This paper proposes a strategy to optimize the design of the substrate structures used in Additive Manufacturing (AM) by Directed Energy Deposition (DED) to minimize the residual stresses induced by this fabrication process. ...
Field-to-field coupled fluid structure interaction: a reduced order model study
(2021-01)
Article.
Accés obert
Article.
Accés obert
The standard Fluid-Structure Interaction (fsi) coupling, that uses as unknowns velocity and pressure for the fluid and displacements for the solid, is compared against two novel types of coupling, the first one a three-field ...
Combination of an adaptive remeshing technique with a coupled FEM–DEM approach for analysis of crack propagation problems
(Springer, 2020-07)
Article.
Accés obert
Article.
Accés obert
This paper presents an enhanced coupled approach between the finite element method (FEM) and the discrete element method (DEM) in which an adaptive remeshing technique has been implemented. The remeshing technique is based ...
Partitioned strong coupling of discrete elements with large deformation structural finite elements to model impact on highly flexible tension structures
(Hindawi, 2020-11)
Article.
Accés obert
Article.
Accés obert
This article presents a staggered approach to couple the interaction of very flexible tension structures with large deformations, described with the finite element method (FEM), and objects undergoing large, complex, and ...
Simulations of landslide wave generation and propagation using the particle finite element method
(Wiley, 2020-06)
Article.
Accés obert
Article.
Accés obert
In this study, the impulse waves generated by highly mobile slides in large-scale flume experiments are reproduced numerically with the Particle Finite Element Method (PFEM). The numerical technique combines a Lagrangian ...
Shear transfer behavior in composite slabs under 4-point standard and uniform-load tests
(2020-01)
Article.
Accés restringit per decisió de l'autor
Article.
Accés restringit per decisió de l'autor
The 4-point bending test, prescribed by most standards, is the conventional test used to determine the shear resistance of steel-concrete composite slabs, whereas loading requirements are commonly specified in terms of ...
Experimental and numerical study of shear interface response of hybrid thin CFRP–concrete slabs
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-09-09)
Article.
Accés obert
Article.
Accés obert
Hybrid slabs made of carbon-fiber-reinforced polymer (CFRP) and concrete provide a solution that takes advantage of the strength properties of both materials. The performance of the system strongly depends on the CFRP–concrete ...
An accurate nonlocal bonded discrete element method for nonlinear analysis of solids: application to concrete fracture tests
(Springer, 2020-05)
Article.
Accés obert
Article.
Accés obert
We present a numerical procedure for elastic and nonlinear analysis (including fracture situations) of solid materials and structures using the discrete element method. It can be applied to strongly cohesive frictional ...
PFEM–DEM for particle-laden flows with free surface
(Springer, 2020-01)
Article.
Accés obert
Article.
Accés obert
This work proposes a fully Lagrangian formulation for the numerical modeling of free-surface particle-laden flows. The fluid phase is solved using the particle finite element method (PFEM), while the solid particles embedded ...
