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 ...

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.

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 ...

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.
