Abstract: A method for identifying the element properties of a truss is developed in this paper. The measured natural frequencies and modal shapes of the truss are used in the identification process. The finite-element method is ...

Abstract: A method for identifying the element properties of a truss is developed in this paper. The axial strains of the truss elements measured in static tests are used in the identification process. The finite-element method is ...

Abstract: A comprehensive framework is set forth for the analysis of structural reliability under incomplete probability information. Under stipulated requirements of consistency, invariance, operability, and simplicity, a method ...

Abstract: A general framework for finite element reliability analysis based on the first‐ and second‐order reliability methods, FORM and SORM, is presented. New expressions for the required gradients of the response of geometrically ...

Abstract: Random fields are often used in reliability analysis to model the uncertainties that possess spatial variabilities. Within the framework of finite element reliability methods, the domain of each field is discretized into ...

Abstract: This paper studies the absolute calibration of acoustic emission signals. The experiments were conducted on a thin plate. Fracture of a glass capillary was adopted to generate a vertical force ...
