AN ANALYTICAL DESIGN OF EXPERIMENTS METHOD FOR FATIGUE CONSTRAINED DESIGN OPTIMIZATION OF A 3D PRINTED STRUCTURE
(2018-12-06)A design of experiments approach has been used to analytically determine a low cycle fatigue (LCF) constraint for use in design optimization of 3D printed structures. In context of metal additive manufacturing, the process ... -
ASSESSMENT OF MATERIAL STATE FOR PREDICTING THE DURABILITY OF COMPOSITES
(Proceedings of the American Society for Composites—Thirty-fifth Technical Conference, 2020-09-17)**Please note that the full text is embargoed** ABSTRACT: The long term behavior of composites have been extensively studied for the last four decades. Given the heterogeneity of these materials, the damage accumulation ... -
Characterization and Enhancement of Fatigue and Fracture properties in Thermoplastic FFF Parts using In-Situ Annealing
(2021-12-21)Fused filament fabrication (FFF) show high anisotropy and reduced mechanical properties as compared to conventional manufacturing techniques. This happens due to the poor interlaminar bonding between the layers, as a result ... -
Characterization of Fatigue Strength of Additively Manufactured Ti-6Al-4V with Recoater Blade Interference Flaws and Residual Stresses Towards an Enhanced Fatigue Substantiation Methodology for Aerospace Structures Applications
(2022-08-17)This research characterized the fatigue strength of additively manufactured (AM) Ti-6Al-4V, through fatigue and static tests conducted using specimens with and without recoater blade interference flaws (RBIF), and thus ... -
Data-Driven Discovery of Material States in Composites Under Fatigue Loads
(American Society for CompositesDEStech Publications, Inc., 2021)**Please note that the full text is embargoed** ABSTRACT: Our community has a widespread knowledge on the damage tolerance and durability of the composites, developed over the past few decades by various experimental and ... -
FATIGUE IMPACTS ON HDPE PIPE MATERIAL PROPERTIES
(2018-01-11)During a pipe’s life cycle, failures occur due to numerous factors such as age, loading conditions, environmental conditions, installation quality, manufacturing procedures, operation and maintenance strategies and so on. ... -
High Magnification Surface Topography based Digital Image Correlation (DIC) for Identifying Damage Accumulation and Crack Growth in Polycrystalline Nickel
(2023-08-09)Damage index parameters that have been formulated to identify damage localization in plastically deformed materials typically require all six stress or strain components. Recently, simulations through Crystal Plasticity ... -
IMPACT OF MUSCULAR FATIGUE AND ITS MODULATION USING TRANSCRANIAL PHOTOBIOMODULATION (tPBM) ON THE HUMAN BRAIN MEASURED BY FUNCTIONAL NEAR-INFRARED SPECTROSCOPY (fNIRS)
(2020-07-22)When performing exercise, the brain must register and simultaneously integrate input from feedforward (i.e., central command) and feedback (e.g., exercise pressor reflex) neural mechanisms to make appropriate cardiovascular ... -
INVESTIGATION OF THE SURFACE TOPOLOGY CHANGES ASSOCIATED WITH FATIGUE
(2019-05-17)Metals have long been known to change their surface topology when subjected to a plastic strain. Given that a plastic zone exists at the tip of a propagating crack, it would seem natural to quantitatively study surface ... -
KOPOS: A FRAMEWORK TO STUDY AND DETECT PHYSICAL AND COGNITIVE FATIGUE CONCURRENTLY
(2021-05-12)Fatigue is one of the most prevalent phenomena in human beings, and yet its detection is highly subjective and poorly understood. The phenomenon of fatigue has a huge impact on performance, the ability to execute tasks ... -
PREDICTION OF SOLDER JOINT FATIGUE LIFE OF PHOTONIC PACKAGE USING Ⅲ-Ⅴ MATERIALS
(2021-12-14)Fatigue life prediction has become very important factor in reliability of any electronic components to withstand extreme thermal stresses in industrial standard. Hence, photonic packages are widely used in telecommunication ... -
Stiffness Degradation in Fatigue Life of Composites using Dielectric State Variables
(Elsevier, 2021-10)**Please note that the full text is embargoed** ABSTRACT: Composite materials are widely used in aerospace and automotive structures for decades and over the years the community has gained a better understanding of the ...
