Abstract
Recent advancements of continuum modelling are now allowing significant
improvements of urban wall structures impact simulation. Urban wall structural
details can now be included in impact modelling that were not previously
achievable. These modelling improvements incorporate the inclusion of resolved
reinforcement bars in concrete walls, brick and mortar construction details in
brick wall construction and resolved cavity and mortar configurations in brick
over block wall constructions. These modelling improvements are being
achieved not only due to increases in computer hardware speeds and memory,
but more so due to a variety of mesh reduction methodologies that have proven
to be improved modelling techniques. An adaptive mesh refinement (AMR)
technique has been implemented for use in the CTH high rate Eulerian finite
difference model. We have applied this AMR to successfully resolve complex
material geometries and dominating physical phenomena. In addition, relaxation
algorithms have been successfully applied for high rate continuum Arbitrary
Lagrangian-Eulerian (ALE) modelling. These relaxation algorithms are now
being used in the ALE-3D computer program to provide high resolution
simulation of urban wall impacts and penetrations. These new techniques are
now allowing the high rate continuum modelling of physical phenomena that
was not previously simulated.
