Adapting neural operators for mechanics decisions under changing operating conditions
Prashant K. Jha, Koffi Enakoutsa, Ian Galloway +1
Neural operators can accelerate repeated nonlinear mechanics calculations, but their accuracy can deteriorate as operating conditions move beyond the training range. This work stud…
Some Numerical Simulations Based on Dacorogna Example Functions in Favor of Morrey Conjecture
Xinghao Dong, Koffi Enakoutsa
Morrey Conjecture deals with two properties of functions which are known as quasi-convexity and rank-one convexity. It is well established that every function satisfying the quasi-…
Fundamental Theorems of Fourier-Stieltjes Transform Defined by Induced Representation on Locally Compact Group
Y. I. Akakpo, M. N. Hounkonnou, K. Enakoutsa +1
This work addresses an extension of Fourier-Stieltjes transform of a vector measure defined on compact groups to locally compact groups, by using a group representation induced by…
An Exact Consistent Tangent Stiffness Matrix for a Second Gradient Model for Porous Plastic Solids: Derivation and Assessment
Koffi Enakoutsa
It is well known that the use of a consistent tangent stiffness matrix is critical to obtain quadratic convergence of the global Newton iterations in the finite element simulations…
Fourier-Stieltjes transform defined by induced representation on locally compact groups
Y. I. Akakpo, K. Assiamoua, K. Enakoutsa +1
In this work we extend the Fourier-Stieltjes transform of a vector measure and a continuous function defined on compact groups to locally compact groups. To do so, we consider a re…
An infinite-server queueing model MMAPkGk in semi-Markov random environment with marked MAP arrival and subject to catastrophes
K. Kerobyan, R. Covington, R. Kerobyan +1
In the present paper the infinite-server MMAPkGk queueing model with random resource vector of customers, marked MAP arrival and semi-Markov (SM) arrival of catastrophes is conside…
Infinite-server queueing model with MAPkGk Markov arrival streams, random volume of customers in random environment subject to catastrophe
Khanik Kerobyan, Ruben Kerobyan, Koffi Enakoutsa
In this paper the infinite server queue model in semi-Markov random environment with k Markov arrival streams, random resources of customers, and catastrophes is considered. After…
Modeling the thermo-mechanical behavior of a woven ceramic matrix composite at high temperatures
Koffi Enakoutsa, Youssef Hammi, John E. Crawford +2
This paper aimed at extending a model developed by Ladeveze to capture thermal expansion and coupled thermo-mechanical phenomena, as such as those encountered at elevated and extre…
Nonlocal Modeling in High-Velocity Impact Failure of 6061-T6 Aluminum
F. R. Ahad, K. Enakoutsa, K. N. Solanki +1
In this paper, we present numerical simulations with local and nonlocal models under dynamic loading conditions. We show that for finite element (FE) computations of high-velocity,…
