Nonlinear energy sinkFrequency detuningVibration reductionBifurcationStrongly modulated responseThe nonlinear energy sink (NES) is a vibration energy absorber, which is of great significance in vibration reduction applications. In this study, the dynamic analysis of the NES with cubic nonlinear damping ...
Nonlinear energy sink (NES) is a type of vibration absorbers that does not have linear stiffness. Through establishing strongly nonlinear coupling between a primary system and a NES, the targeted energy transfer can be achieved from the primary system to the NES, thereby realizing vibration absorpti...
The nonlinear analysis software SAFIR [36] is used to investigate the thermal-structural response of the columns under fire conditions. Ten specimens are taken from experiments [15,28,29,37] for the FE models' validation. The specimens include a square CFST column with an internal steel profile...

Special nonlinear elements, joints, and hinges are added to the FE code to describe the behavior of the landing gear. The approach in this work includes the landing gear directly within the transient, dynamic simulation. Therefore, a generic landing gear model is added to the simulation code. ...
The proposed optimization problem has been solved using combined stochastic based (Genetic Algorithm) and nonlinear mathematical programming (Sequential Quadratic Programming Algorithm) techniques.In the fourth phase, the MREA device model has been incorporated in a single degree of freedom helicopter model...
DLW (Fig.2d), also known as TPP/MPP, enables 3D printing with sub-100-nm resolutions82as a result of the nonlinear absorption of two or more photons by photosensitive monomers83. TPP/MPP focuses a femtosecond laser beam (near-infrared (NIR)) within a diminutive volume (i.e., voxel, 3D...
