Digital Light Processing of 2D Lattice Composites for Tunable Self‐Sensing and Mechanical Performance

open access: yesAdvanced Engineering Materials, EarlyView., 2023
The study presents the mechanical and in situ sensing performance of digital light processing‐enabled 2D lattice nanocomposites under monotonic tensile and repeated cyclic loading, and provides guidelines for the design of architectures suitable for strain sensors and smart lightweight structures.

Creep Characterization of Inconel 718 Lattice Metamaterials Manufactured by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView., 2023
Herein, the creep characteristics of additively manufactured Inconel 718 metamaterials are investigated. The creep behavior of metamaterials and the effects of microstructural defects are assessed, and the microstructure defects are accurately captured using Kachanov's creep damage model.

Flexural Behavior of Bidirectionally Graded Lattice

open access: yesAdvanced Engineering Materials, EarlyView., 2023
An experimental study of the bending behavior of bidirectional body‐centered cubic lattice beams is conducted in comparison to uniform and unidirectional counterparts of electron beam melted SS 316 L. Experimental results are used to develop and validate a finite element model which is subsequently used to conduct parametric studies to assess the ...

A Variational Beam Model for Failure of Cellular and Truss‐Based Architected Materials

open access: yesAdvanced Engineering Materials, EarlyView., 2023
Herein, a versatile and efficient beam modeling framework is developed to predict the nonlinear response and failure of cellular, truss‐based, and woven architected materials. It enables the exploration of their design space and the optimization of their mechanical behavior in the nonlinear regime. A variational formulation of a beam model is presented

Architected Lattices with a Topological Transition

open access: yesAdvanced Engineering Materials, EarlyView., 2023
This article develops topological metamaterials showing multidirectional two‐step deformation under compression by embedding contact‐enabled topological mechanisms into lattice structures. Experiments on 3D‐printed 2D and 3D lattices and finite element simulations are conducted to demonstrate the working principle of the topological metamaterials.

Global Dynamics of Some Exponential Type Systems

open access: yesDiscrete Dynamics in Nature and Society, 2020
We explore the boundedness and persistence, existence of an invariant rectangle, local dynamical properties about the unique positive fixed point, global dynamics by the discrete-time Lyapunov function, and the rate of convergence of some 2,3-type ...

Exponential Rosenbrock-Type Methods

open access: yesSIAM Journal on Numerical Analysis, 2009
We introduce a new class of exponential integrators for the numerical integration of large-scale systems of stiff differential equations. These so-called Rosenbrock-type methods linearize the flow in each time step and make use of the matrix exponential and related functions of the Jacobian.

Multivariate Exponential-type Distributions [PDF]

open access: yesThe Annals of Mathematical Statistics, 1968
Let $\mathbf{x}$ and $\mathbf{\theta}$ denote $s$-dimensional column vectors. The components $x_1, x_2,\cdots x_s$ of $\mathbf{x}$ are random variables jointly following an $s$-variate distribution and components $\theta_1, \theta_2,\cdots, \theta_s$ of $\mathbf{\theta}$ are real numbers.

Entire bivariate functions of exponential type [PDF]

open access: yesBulletin of Mathematical Sciences, 2015
In this paper we will analysis the concepts of bivariate entire complex valued functions of exponential type. To accomplish this goal, we begin with the presentation of a notion of bounded index for bivariate complex functions. Using this notion we present a series of sufficient conditions that ensure that exponential type is preserved.
