A reduced-order modelling to predictively simulate the dynamics of piezoelectric structures with geometric nonlinearities is proposed in this paper. formulation three-dimensional finite element models global electric variables per patch, and suitable any commercial code equipped geometrically nonlinear capabilities, proposed. modal expansion leads a reduced model where both electromechanical co...

In structural analysis, the base of structures is usually assumed to be completely rigid. However, the combination of foundation and the subsurface soil, makes in fact a flexible-base for the soil-structure system. It is well-known that the structural responses can be significantly affected by incorporating the Soil-structure Interaction (SSI) effects. The aim of the present study is to provide...

In this work parametric reduced order models (pROMs) for cracked shells are developed and applied to crack detection problems. Mesh morphing is employed allow parameterization of the with respect location size, while a clustering approach adopted partition parameter space in sub-domains, which efficient local (ROMs) constructed. Subsequently, proposed ROMs as forward simulators within an invers...

before a president practically begins his four-year term of office in iran, a formal inaugural ceremony is held in the parliament. being attended by national dignitaries and representatives from other countries, the inauguration of iran's seventh president, hasan rouhani, was spectacular in several respects. the current study aimed at investigating the generic structure and rhetorical move...

This paper deals with the optimization of the catalytic convertor for CNG Lean burn Engine based on BS4 compliances. In addition to the present catalytic convertor the work is carried out for the optimization of catalytic convertor and also to meet the BS4 compliance and also to reduced cost for the same. In this project we have prepared the samples with some variation in the substrate with res...
