Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

Partial averaging of functional differential equations

Proceedings of the 38th IEEE Conference on Decision and Control (Cat. No.99CH36304), 2003
Develops a framework for averaging functional differential equations (FDEs) with two time scales. Averaging is performed on the fast time system, while slow time is 'frozen.' This creates an averaged equation which is slowly time-varying, hence the terminology of partial averaging.

Comparison method of partial functional differential equations and its application

Applied Mathematics and Computation, 2002
Here, the initial value problem \[ \frac{du}{dt} = Au + f(t,u_t), \quad t \geq 0, \qquad u = \varphi (t), \quad t \in [-r,0], \] is considered on the real Banach space \(X\), where \(u_t = u(t + \theta)\), \(-r \leq \theta \leq 0\), and \(A\) is a linear operator on \(X\).

A HARTMAN-GROBMAN THEOREM FOR SOME PARTIAL FUNCTIONAL DIFFERENTIAL EQUATIONS

International Journal of Bifurcation and Chaos, 2000
We show that the flow of some partial functional differential equations has a global attractor. As a conseqsuence we prove that the flow near a hyperbolic equilibrium is equivalent to its variational equation.
