A variable amplitude multiaxial fatigue life prediction method
A method to estimate the fatigue life of a component subjected to variable amplitude multiaxial loading has been developed. It is based upon an extension of the strain-life approach which achieved success in correlating the fatigue lives of components subjected to uniaxial variable amplitude …

Multiaxial fatigue damage model for random amplitude loading histories
In spite of many multiaxial fatigue life prediction methods proposed over decades of research, no universally accepted approach yet exists. A multiaxial fatigue damage model developed for approximately proportional random amplitude loading is proposed in this study. A normal strain based analysis …

Tensile and uniaxial/multiaxial fatigue behavior of ceramic matrix composites at ambient and elevated temperatures
… lower toughness. Calculations from the tensile fatigue model suggest that a lower <i>m</i> value results in a longer fatigue life.

Multi-Domain Multi-Material Topology Optimization of a Roller Coaster Vehicle Bogie Subject to Multiaxial Fatigue Constraints
… assemblies (bogies), specifically focusing on multiaxial fatigue topology optimization. Roller coaster bogies endure complex multiaxial loading conditions and require specialized fatigue constrained optimization due to their intricate loading, operating conditions, and repetitive load time …

Multiaxial Fatigue Life Extension of Steel Elements Using Shape-Memory Alloy/Carbon Fiber-Reinforced Polymer (SMA/CFRP) Patch
Fatigue cracking is a primary factor hindering the performance of steel bridges. Without alternative load-paths, fatigue failure of a member can lead to sudden and catastrophic collapse of the entire structure. There are currently more than 170,000 steel bridges containing fatigue-sensitive details …

An experimental investigation of homogeneous fatigue damage in a random short-fiber composite under combined tension-torsion loading
… stress on the fundamental nature of distributed fatigue damage in a random short fiber composite. The project consists of two different tasks: first, to develop a new experimental method, for conducting combined shear and axial fatigue damage in composites which are difficult to fabricate in …

Designing against failures resulting from static and time-varying loading in thick-walled components made of ductile cast iron
… Plasticity. The study extends to the uniaxial fatigue response, analysing the interaction between micro-shrinkage porosity and geometrical notches using probabilistic approaches, the concept of Highly Stressed Volume and local fatigue criteria. Furthermore, multiaxial fatigue is explored …

Axial Cyclic Response of Unnotched and Notched Carburized Cylindrical Members Under Constant Amplitude Completely Reversed Loading
This investigation pertains to the evaluation of fatigue resistance, primarily at long life, of axially-loaded circumferentially-notched cylindrical surface-hardened (carburized) members (K(,t) = 1.46 and K(,t) = 2.22) prepared from AISI 8620H steel. Concurrently, the fatigue behavior of smooth …
