ACOUSTOELASTIC EFFECTS ON THE NATURAL FREQUENCIES OF PRE-STRESSED CONCRETE BEAMS
(2011) 37th Annual Review of Progress in Quantitative Nondestructive Evaluation (QNDE) 1335. p.1379-1385- Abstract (Swedish)
- Abstract in Undetermined
Pre-stressed concrete is used to increase the load capacity in many civil engineering structures. There is a need for non-destructive methods to estimate the potential loss of pre-stress in these structures. In this study we investigate the acoustoelastic effect on the natural resonance frequencies of a pre-stressed concrete beam. Measured resonant frequencies increase with increasing compressive stress. Results agree with predicted frequency shifts obtained from a non-linear finite element model based on Murnaghan's third order elastic theory.
