Piezoelectric material transducers can work as an actuator or sensor. Generally, the actuator
will be used to repair the structure, and the sensor will be used to find the health condition. In …

The present study is the first attempt to investigate the free vibration behavior of the
rectangular plate including two equal (twin) internal parallel piezoelectric inclusions (lying …

The analysis of stress concentration in geometrically heterogeneous smart structures is of
great importance. In this study, by utilizing a recent constitutive model which considered both …

This paper is focused on stiffness ratio effect and a new method to specify the best pattern of
piezoelectric patches placement around a hole in a plate under tension to reduce the stress …

The purpose of this article is using piezoelectric actuators to reduce stress concentration
factor in classic plates under tensile force. There are three classic plates in this study …

Reducing the stress concentration factor (SCF) in a design has been always a major
challenge for mechanical designers. In this paper, a comprehensive investigation is …

Optimization of the volume/weight in the gear train is of great importance for industries and
researchers. In this paper, using the particle swarm optimization algorithm, a general gear …

Locating piezoelectric patches on structures under compressive forces as a sensor or
actuator can predict or increase the buckling load of the structure. In this article, using …

This paper focuses on reducing stress concentration in a plate with a hole. For this purpose,
a novel Reliever Topological Material Elimination (RTME) approach was introduced which …

Decreasing stress in a part or piece of equipment especially in a stress concentration point
without increasing thickness or using stronger material is always an interesting issue for …
