One of the most common methods of construction is the use of concrete masonry units (CMU) in the walls of buildings. However, they are vulnerable to blast, and result in collapse, fragmentation, and severe injury to occupants. An understanding of the behavior of CMU walls during blast is key to developing mitigation techniques. Research has been conducted using the finite element method to simulate structural failure due to blast. A common problem faced by model developers is the selection of constitutive relationships that appropriately simulate the behavior of materials subjected to shock loading. This project examined the effect of blast impulse loading on CMU blocks. Finite element models were used to perform direct transient analysis using various material cards available in LS-DYNA, and the results were compared to the results of full-scale blast tests conducted by AFRL. The material card that best agreed with the test results was recommended for use in the models of polymer reinforced masonry walls.

The work presents the theoretical basis of Additional Finite Element Method (AFEM), which is a variant of the Finite Element Method (FEM) for analysis of reinforced concrete structures at limit state. AFEM adds to the traditional sequence of problem by FEM the units of the two well-known methods of the structural design: method of additional loads and limit state method. The problem is solved by introduction of ideal failure models and additional design diagrams formed from additional finite elements, where each AFE describes the limit state reached by the main element. The main relations defining the properties of AFEs as well as the examples of the use of Additional Finite Element Method for analysis of reinforced concrete structures at limit state are given in the work too.
