Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

open access: yesAdvanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

A Numerical Approach of Handling Fractional Stochastic Differential Equations

open access: yesAxioms, 2023
This work proposes a new numerical approach for dealing with fractional stochastic differential equations. In particular, a novel three-point fractional formula for approximating the Riemann–Liouville integrator is established, and then it is applied to ...

Admonian's method for Hammerstein integral equations arising from chemical reactor theory

open access: yes, 2001
An ordinary differential equation with a parameter in the boundary conditions describes the steady state in an adiabatic tubular chemical reactor. In this paper, the problem is considered as a Hammerstein integral equation and solutions are obtained ...

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

open access: yesAdvanced 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.

ON THE OPERATORS RELATED TO STOCHASTIC INTEGRAL EQUATIONS [PDF]

open access: yesDemonstratio Mathematica, 1983
The purpose of this work is to consider the concept of a general stochastic equation and to investigate the problem of existence and uniqueness of its solution. Thus our aim is twofold. Firstly, we intend to study various types of operators which map the class of adapted, right continuous and possessing left limits processes into itself.
