The purpose of this paper is control of simply supported flexible core sandwich beam's linear vibration equipped with piezoelectric patches under different loads. The effects of external forces imposed on sandwich beam can be reached to a minimum value by designing an appropriate controller and control the beam's vibration. Three-layer sandwich beam theory is used for analytical modeling of san...

This article deals with the mechanical analysis of a fixed-fixed nano-beam based on nonlocal elasticity theory. The nano-beam is sandwiched with two piezoelectric layers through it’s upper and lower sides. The electromechanical coupled equations governing the problem are derived based nonlocal theory considering to Euler-Bernoulli beam assumptions and based on the nonlocal piezoelectricity acco...

• Granulation growth literature is reviewed to find solutions for size prediction. Two limiting cases granule are found and equations determined. Growth behaviour also derived by including consolidation behaviour. The prediction matches longstanding regime maps strongly. solution includes nucleation, growth, breakage in a continuous solution. Size control granulation of great importance yet oft...

This work focuses on bearing rigidity theory, namely the branch of knowledge investigating structural properties necessary for multi-element systems to preserve inter-unit bearings under deformations. The contributions this are twofold. first one consists in development a general framework statement principal definitions and rigidity. We show that approach encompasses results existing literatur...
