A fast algorithm to racetrack filter multiaxial histories preserving load shape [PDF]

MATEC Web of Conferences, 2019
A fast algorithm is presented to implement a multiaxial version of the racetrack amplitude filter, improved upon the authors’ previous works. The algorithm only requires a single user-defined scalar filter amplitude to eliminate noise and potentially non-

Development of a Novel Apparatus to Determine Multiaxial Tensile Failure Criteria of Bridge Repair Materials

Applied Sciences, 2023
Aging infrastructure is increasingly costing taxpayers due to increased repair and replacement costs. Ultra-high performance concrete (UHPC) has recently been recognized as a viable material for both the repair of concrete and steel infrastructure as ...

Multiaxial Deformations and Stress Analyses

, 2012
When a structure is subjected to uniaxial tension, the transverse dimensions decrease (the structure undergoes lateral contractions) while simultaneously elongating in the direction of the applied load. This was illustrated in the previous chapter through the phenomenon called necking.

Research on multiaxial notch fatigue life of additively manufactured 316L considering mean stress and multiaxial stress state

, 2023
Abstract Fatigue tests were performed on Additively Manufactured (AM) 316L steel. Then, a new energy based multiaxial notch fatigue life model was proposed, in which a virtual strain energy that can reflect the multiaxial effect of stress and the mean stress was used as the damage parameter, and a notch coefficient was used to modify the notch ...

Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

Advanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Fatigue Equivalent Stress State Approach Validation in Non-conservative Criteria: a Comparative Study

Latin American Journal of Solids and Structures
This paper is concerned with the fatigue prediction models for estimating the multiaxial fatigue limit. An equivalent loading approach with zero out-of-phase angles intended for fatigue limit evaluation under multiaxial loading is used.

MODELLING OF STRESS GRADIENT EFFECT ON FATIGUE LIFE USING WEIBULL BASED DISTRIBUTION FUNCTION [PDF]

, 2013
In the present paper, a new approach is developed in order to take into account the stress gradient effect on fatigue life of structural components. The proposed approach is based on the weakest link concept in which the shape coefficient of the Weibull ...

Brittle Fracture Criterion Under Multiaxial Stresses

TANSO, 1986
Criteria of macroscopic brittle fracture under multiaxial stresses are discussed to provide for a new design criterion of a nuclear graphite which is expected to be used for a High Temperature Gas Cooled Reactor.Under the stress state in which tensile stresses are predominant, the maximum principal stress theory is applicable for the brittle fracture ...

Thermal Fatigue under Multiaxial Thermal Stresses

Journal of the Society of Materials Science, Japan, 1965
Cast iron is widely used as the material for various machine parts, and the fracturing of the members made of cast iron, presumably due to thermal fatigue, is often experienced in practice. In spite of its importance as an engineering problem, however, the study of thermal fatigue of cast iron is very limited.

From Mechanics to Electronics: Influence of ALD Interlayers on the Multiaxial Electro‐Mechanical Behavior of Metal–Oxide Bilayers

Advanced Functional Materials, EarlyView.
Ultrathin AlOxHy interlayers between aluminum films and polymer substrates significantly improve electro‐mechanical properties of flexible thin film systems. By precisely controlling interlayer thickness using atomic layer deposition, this study identifies an optimal interlayer thickness of 5–10 nm that enhances ductility and delays cracking.
