Jürgen Boelcke,Bernard Straub,Paul Thielethod (FEM). RC wall is modeled with Lagrangian elements, and the Jones-Wilkins-Lee (JWL) equation of state is used to model the detonation of an explosive charge in LS-DYNA.. Whereas blast wave propagation is simulated using Multi-Material Arbitrary Lagrangian–Eulerian (MM-ALE) approach. Fluid–Struc

Jürgen Boelcke,Bernard Straub,Paul Thielefinite element model of the rock slope is simulated with Abaqus 2020 using Arbitrary Lagrangian–Eulerian (ALE) technique. Failure stresses owing to blasting are compared with and without TC in the rock slope. It is observed that resultant stress waves originating from a significant distance may trig

The tunnel design, construction planning and the study of its behavior under different loading conditions involve many interdisciplinary aspects of geological, geotechnical and structural engineering. It is a complex mechanism of soil-structure interaction strongly influe

Jürgen Boelcke,Bernard Straub,Paul Thiele can enhance the lethality of the warhead. The lethal efficiency of high explosive (HE) warheads is a function of fragment velocity and mass of controlled fragments and their spatial distribution. Fragment velocity depends on the explosive and its density, warhead metal case and explosive mass ratio

Jürgen Boelcke,Bernard Straub,Paul Thieleelement (FE) simulations using software LS-DYNA R8.1.0 are used to evaluate and compare the response of RC slabs under different blast loadings of 2, 4 and 6 kg TNT, at a stand-off distance of 1.5 m from the surface of the slab. RC slab of size 3.6 m × 3.0 m × 0.2 m, reinforced on one face with two-
