A Point Crack Source Location Method without Velocity Information in Anisotropic Plates
نویسندگان
چکیده
Locating cracks in a solid object using acoustic emission (AE) is useful both for detecting defects during safety monitoring and basic laboratory studies of fractures. We developed an source location (ASL) method without the use velocity information with AE anisotropics plates, such as carbon fiber-reinforced polymers. Assuming that propagation unknown elastic wave constant anisotropic materials, objective function to be minimized defined based on elliptic wavefront shape-based technique. The iterative method, gradient descent method. As result numerical experiments PLB testing polymer plate, accurate within 5% stable against noise.

Electro-Mechanical Impedance Method for Crack Detection in Thin Plates
In recent years, the damage detection with E/M impedance method has gained increased attention. The method uses small-size piezoelectric active sensors intimately bonded to an existing structure, or embedded into a new composite construction. Experimental demonstrations have shown that the real part of the highfrequency impedance spectrum is directly affected by the presence of damage or defect...
متن کاملA development in the finite volume method for the crack growth analysis without global remeshing
Crack growth analysis has remained one of the challenging problems in the fracture mechanics of structures. On the other hand, the fatigue crack growth is a common phenomenon in the components of structures like airplanes, navies and fluid storages where the fracture due to crack should be considered in the design of these structures. In this paper, the finite volume method (FVM) is extended fo...
متن کاملElement free Galerkin method for crack analysis of orthotropic plates
A new approach for analyzing cracked problems in 2D orthotropic materials using the well-known element free Galerkin method and orthotropic enrichment functions is proposed. The element free Galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. In this study, element free Galerkin is extrinsically enriched by the recently developed crack-tip orthot...
