Random Vibration Fatigue: Frequency Domain Critical Plane Approaches

Volume 9: Mechanics of Solids, Structures and Fluids, 2013
Frequency domain analysis offers a very efficient method for the fatigue durability assessment of structures subjected to vibration loading. It also allows engineers to gain valuable insight into system behavior and characteristics that are not easily recognized in the time domain. With some reasonable assumptions, most importantly linearity and steady

Damage Mechanics and Critical Plane Approach to Multiaxial Fatigue

Key Engineering Materials, 2013
The mechanical behaviour of structural components subjected to multiaxial fatigue loading is very important in modern design. Several approaches have been introduced in recent decades to analyse this problem. The so-called critical plane approach, based on the stresses acting on the plane where the crack nucleation is expected to occur, is widely used.

The damage scale concept and the critical plane approach

Fatigue & Fracture of Engineering Materials & Structures, 2017
AbstractCritical plane criteria seek the plane in which their damage parameter has its maximum value. On this plane, the fatigue damage of both normal and shear stresses is updated to the same damage scale by a constant, typically based on material normal/shear fatigue limits. This paper focuses on the damage scale concept under a stress‐based critical

Failure Criterion for Structural Masonry based on Critical Plane Approach

Journal of Engineering Mechanics, 2002
The paper presents a macroscopic failure criterion for structural masonry. This criterion is derived within the framework of the critical plane approach. First, a general discussion is provided examining the performance of this framework in the context of classical linear as well as nonlinear criteria. Subsequently, a bilinear form of failure criterion

Hot-spot localisation according to the critical plane-based approach

International Journal of Fatigue, 2018
Abstract The tubular welded joints in H-shaped structural components of agricultural sprayers are responsible for failure and the localisation of hot-spots is very important in multiaxial fatigue assessment of such components. Therefore, the purpose of the present paper is to develop a novel approach both to localize hot-spots in tubular welded ...
