TOPOLOGY OPTIMIZATION OF STRUCTURES UNDER TRANSIENT LOADS
In this article, an efficient methodology is presented to optimize the topology of structural systems under transient loads. Equivalent static loads concept is used to deal with transient loads and to solve an alternate quasi-static optimization problem. The maximum strain energy of the structure under the transient load during the loading interval is used as objective function. The objective f...
متن کاملDamage Detection of Bridge Beam Structures under Moving Loads
System identification technique is used widely in the damage assessment of engineering structures. It is regarded as the key part of a structural health monitoring system, which identifies the physical parameters from the raw measurement data. The changes in the identified parameters will be used to assess the damage of the structure. Most system identification methods need the input loading an...
متن کاملLow Velocity Impact Damage Prediction in Laminated Composite Plates
In this paper, a finite element model is presented for the transient analysis of low velocity impact, and the impact induced damage in the composite plate subjected to low velocity impact is studied. The failure criteria suggested by Choi and Chang and the Tsai-Hill failure criteria are used for the prediction of the damage in the composite plate; then the effect of various parameters on the im...
متن کاملStructural damage identification in laminated structures using FRF data
A damage identification technique based on frequency response functions (FRF) sensitivities is presented. This technique leads to a set of linear equations, which is solved using an algorithm that constrains the solution to be physically admissible. Damage simulation and identification on a laminated rectangular plate is performed. The influence of the number of natural frequencies and mode sha...
متن کاملIsogeometric-Based Modeling and Analysis of Laminated Composite Plates Under Transverse Loading
Analysis of the laminated composite plates under transverse loading is considered using the new method of Isogeometric Analysis (IGA). Non-Uniform Rational B-Splines(NURBS)are used as shape functions for modeling the geometry of the structure and also are used as shape functions in the analysis process. To show robustness of the new technique, some examples are represented and are compared with...
