Multiaxial Loads and Stresses

2017
Many design tasks are concerned with structural components or systems subject to multicomponent loads. In this case, several forces and moments, which are partially time-independent, can act on the structural component to be evaluated. The local stress state and its variation with time at relevant locations result from the superposition of the local ...

Engineering Components under Multiaxial Loading

Materials Testing, 2001
This paper deals with some of the most important theoretical approaches to calculate the fatigue life of engineering components under multiaxial-proportional loading. The calculation procedures which are to be followed are demonstrated using as an example, a notched shaft made from two different materials under uniaxial and multiaxial loading with ...

Climate Chamber for Testing of Multiaxial Loading

2016
This paper examines the equipment for testing of materials under different climatic conditions with control of humidity environment. The described device allows testing samples for tension and pressure in uniaxial loading. For static testing, samples can be used in a separate climate chamber or in an external climate chamber with a possibility of ...

Failure Prediction for Laminated Composites under Multiaxial Loading

Journal of Reinforced Plastics and Composites, 1999
An analysis for failure prediction is presented for laminated composites under extension and bending. The method is based on the determination of the fiber and matrix strains in each composite lamina. Under combined extension and bending, layer strains in a composite section are computed by means of the laminate theory and used as input for a three ...

A fatigue criterion for general multiaxial loading

Fatigue & Fracture of Engineering Materials & Structures, 2000
An incremental fatigue damage model is proposed. The model incorporates the critical plane concept in multiaxial fatigue, plastic strain energy and material memory in cyclic plasticity. With an incremental form the model does not require a cycle counting method for variable amplitude loading.

The relationships between multiaxial loading history and tibial strains during load carriage

Journal of Science and Medicine in Sport, 2019
To determine if a history of exercise involving multiaxial loading, through soccer participation, influences tibial stains during incremented load carriage.Cross-sectional study.20 female soccer players (20±1 yr) and 20 mass- and height-matched healthy women (21±1 yr) participated in walking tasks with 0kg, 10kg, 20kg, and 30kg loads on a force ...

Treatment of Multiaxial Loading

2009
Abstract This chapter addresses the question of how to deal with multiaxial stresses and strains when using the strain-range partitioning method to analyze the effects of creep fatigue. It is divided into three sections: a general discussion on the rationale used in formulating rules for treating multiaxiality, a concise listing of the ...

Fatigue of honeycombs under in-plane multiaxial loads

Materials Science and Engineering: A, 2001
Abstract Modeling for fatigue of honeycombs under in-plane multiaxial loads is proposed and presented here. Paris law for microcrack propagation, Basquin law for high cycle fatigue and Coffin–Manson law for low cycle fatigue are employed to describe the fatigue of solid cell walls within honeycombs, respectively.

Material hardening under multiaxial creep loading

Nuclear Engineering and Design, 1992
Abstract Real components in operation are exposed to cyclic multiaxial loadings. For the evaluation of the allowable operation time the effect of those cyclic loadings on deformation and creep strain behaviour must be derivated. The theoretical discussion of strain-, time- and energy-hardening theory and their mathematical description by creep laws ...
