Objectives
- Development of numerical models using finite element package, LSDYNA, for the simulation of AE waveforms in nuclear containment structures.Â
This will mainly involve the following:Â- accurate modeling of the AE events, e.g, cracking and tendon wire or rebar breaks.
- study dispersion characteristics of AE waveforms generated by these event in concrete structures.
- Establish a direct correlation between the AE signals and the fracture mechanisms
- Investigation of the influence of heterogeneities like aggregates, pores, reinforcement bars and prestressing tendons on wave propagation.
- Experimental implementation and validation of the computational results.
- Extension of the numerical simulation studies to a scaled pressurized containment structure.
