Taylor Impact Test and Penetration of Reinforced Concrete Targets by Cylindrical Composite Rods
We use the three-dimensional finite element code DYNA3D to analyze two problems: (a) the normal impact of a cylindrical monolithic or composite rod against a smooth flat rigid target, (commonly known as the Taylor impact test), and (b) the penetration of composite and monolithic steel cylindrical …

Behavior of reinforced concrete column-beam joint subjected to close in blast loads with polyurea and FRP sheets
… joint under close-in blast loads using finite element modeling in LS-DYNA with an Arbitrary Lagrangian-Eulerian (ALE) formulation. Failure is captured through element erosion based on maximum principal strain. The study employs concrete with a compressive strength of 38.5 MPa and reinforcing …

Experimental and finite element modelling of ultrasonic cutting of food
… and experience of the tool designers. Finite element (FE) models have also been used to predict the vibrational behaviour of the cutting tool. However, the performance of an ultrasonic device critically relies on the interaction of the cutting tool and material to be cut. Currently the …

Numerical Methods for Fluid-Solid Coupled Simulations: Robin Interface Conditions and Shock-Dominated Applications
… viscous flow solver with a nonlinear finite element solid solver. Both an analytical study and a numerical study reveal that the new algorithm can clearly outperform conventional Dirichlet-Neumann procedures in terms of both stability and accuracy, when the parameter value is carefully …

Stratigraphic evolution and architectural analysis of structurally confined submarine fans: a tripartite outcrop-based study
… diversity and compensational stacking of elements through time. These patterns are attributed to an increase in depositional area, and a decrease in accommodation relative to sediment supply (A:S), as the bowl-shaped basin filled. Isopach mapping reveals a prominent thick, which nearly …
