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.

Estimation of Low-Cycle Fatigue Curves of High-Strength and Welded Steel 10CrNi3MoV [PDF]

, 2019
In this work is tested applicability of the extended uniform material law for high-strength steel on 10CrNi3MoV steel and its weld. Predicted low-cycle fatigue curves differ significantly from the measurements. Despite the reported scientific effort to

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Artificially cemented sand under multiaxial loading [PDF]

E3S Web of Conferences, 2019
Distinct improvement techniques can be used when civil engineering structures are to be built on soils that do not present suitable mechanical characteristics. The soil improvement techniques can vary from compaction to chemical and mechanical stabilisation. This work focuses on the specific case of granular soils treated with low amount of cement. The

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Thermo-mechanical FE model with memory effect for 304L austenitic stainless steel presenting microstructure gradient [PDF]

, 2012
The main purpose of this study is to determine, via a three dimensions Finite Element analysis (FE), the stress and strain fields at the inner surface of a tubular specimen submitted to thermo-mechanical fatigue.

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

Advanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

The Failure Behavior of an Epoxy Resin Subject to Multiaxial Loading

Pipelines 2006, 2006
The failure behavior of an epoxy resin (EPON 826) was investigated by a series of tests on thin-walled tubular specimens and the results are presented in this paper. The tests were designed such that a constant octahedral shear strain rate was applied along different loading paths.
