An Isogeometric Over-Deterministic Method (IG-ODM) to Determine Elastic Stress Intensity Factor (SIF) and T-Stress

Mathematics, 2023
In order to examine the significance of Stress Intensity Factor and T-stress (K-T parameters) in modeling pressure-cracked structures, we propose a novel method known as the Isogeometric Over-Deterministic Method IG-ODM.

Over-deterministic method: The influence of rounding numbers on the accuracy of the values of Williams’ expansion terms [PDF]

Fracture and Structural Integrity, 2017
A study on the accuracy of the values of Williams’ expansion terms influenced by rounding numbers is presented. The results are presented taking into account a three-point bend single edge notched beam.

An Over-Deterministic Method for Mode III SIF Calculation Using Full-Field Experimental Displacement Fields

Applied Sciences
The paper proposes and tests an approach to determine the stress intensity factors (SIF) of cracks subjected to mode III using full-field displacements as opposed to the crack opening displacement (COD) method, which uses only two data points.

Multi-Robot Exploration of Unknown Space Using Combined Meta-Heuristic Salp Swarm Algorithm and Deterministic Coordinated Multi-Robot Exploration

Sensors, 2023
Multi-robot exploration means constructing a finite map using a group of robots in an obstacle chaotic space. Uncertainties are reduced by distributing search tasks to robots and computing the best action in real time.

Fast, deterministic computation of the Hermite normal form and determinant of a polynomial matrix [PDF]

Journal of Complexity, 2016
Given a nonsingular $n \times n$ matrix of univariate polynomials over a field $\mathbb{K}$, we give fast and deterministic algorithms to compute its determinant and its Hermite normal form.

Development of Deterministic Artificial Intelligence for Unmanned Underwater Vehicles (UUV)

Journal of Marine Science and Engineering, 2020
The major premise of deterministic artificial intelligence (D.A.I.) is to assert deterministic self-awareness statements based in either the physics of the underlying problem or system identification to establish governing differential equations. The key

Inverse problems with the digital image correlation: approach and applications

Fracture and Structural Integrity, 2021
A viable approach to solve inverse problems in elasticity is proposed. It is based on regression algorithms to estimate materials and/or loading parameters by fitting the experimentally-evaluated displacement field to representative analytical solutions.
