Description

Papers abstract:

This study is based on the data from an experimental investigation of masonry wall behavior under blast loading. It includes an overview of some crucial aspects dealing with the numerical modelling of brick wall failure under such loading. The masonry walls exposed to the actual and a computational blast wave action are examined. The brittle behavior of two-phase masonry is described utilizing a VUMAT user subroutine in Abaqus Explicit code. The presented description is novel and fully introduced by the authors. The brittle behavior of masonry includes material damage and base on the implemented equivalent stress value. Moreover, the initial properties are introduced by an additional laboratory dynamic measurement both phases of the masonry. The numerical response of this obstacle is preliminarily verified during laboratory tests, including the strain rate effect, using a Split Hopkinson Pressure Bar. The explosive loading is presented by a rapid pressure wave which is propagated through the ambient air. This complex experiment is implemented numerically mixing newly developed material response inside the eulerian domain described by equations of the state for the air and explosive respectively. The actual experiments are performed using masonry walls for close-in explosions. Finally, the numerical studies are compared with the experiments, resulting in pressure-impulse curves and masonry failure.

Product Overview:
This tutorial provides access to a detailed simulation of masonry wall behavior under explosive loading. The model replicates real-world blast effects, enabling users to analyze shock wave propagation, material failure, and debris distribution. The study’s numerical framework ensures accurate predictions of masonry cracking, stress evolution, and collapse mechanisms. Key simulation steps include:

  • The tutorial provides a comprehensive guide to simulating masonry wall behavior under explosion using finite element modeling (FEM).
  • The Johnson-Holmquist model for concrete and Jones-Wilkins-Lee equation for TNT allow accurate failure prediction.
  • The simulation successfully replicates real-world blast scenarios, showing the effectiveness of numerical modeling.
  • The tutorial is useful for structural engineers, defense analysts, and researchers working on blast-resistant designs.

 

In this tutorial, the behavior of masonry wall under explosive loading is simulated, according to data from the work of Sielicki and Łodygowski.

More information

  • This package provides an extensive, validated numerical framework for blast resistance studies on masonry walls. The model integrates experimental strain rate effects, air-structure interactions, and shock wave propagation to offer realistic failure predictions. It is suitable for engineers, researchers, and defense analysts working on structural blast protection.
