A lower bound for the energy decay rate in piezoelectricity
Khanh Chau Le
This paper establishes a lower bound for the energy decay rate in piezoelectric cylinders. The bound incorporates material properties and geometric factors, including the cross-sec…
Asymptotically exact theory of functionally graded elastic beams
Khanh Chau Le, Tuan Minh Tran
We construct a one-dimensional first-order theory for functionally graded elastic beams using the variational-asymptotic method. This approach ensures an asymptotically exact one-d…
An asymptotically exact first-order shear deformation theory for functionally graded plates
Khanh Chau Le
An asymptotically exact first-order shear deformation theory for functionally graded elastic plates is derived using the variational-asymptotic method. As an application, an analyt…
Theory of transition from brittle to ductile fracture
Khanh Chau Le, Hyeonyeong Jeong, Tuan Minh Tran
In this paper, two improvements to the theory of transition from brittle to ductile fracture developed by Langer are proposed. First, considering the drastic temperature rise near…
Optimal parameters uncoupling vibration modes of oscillators
Khanh Chau Le, Alexander Pieper
A novel optimization concept for an oscillator with two degrees of freedom is proposed. By using specially defined motion ratios, we control the action of springs and dampers to ea…
