Determination of fracture toughness by uniaxial tensile test

Engineering Fracture Mechanics, 1996
The dynamic fatigue life equation is applied to uniaxial tensile test. The resultant equations for the surface energy and fracture toughness are calculated with the data from the tensile test and compared with the ones from ASTM E399 test. During the crack propagation under model loading, the material of the crack tip undergoes the process of the ...

Concrete Uniaxial Tensile Strength and Cylinder Splitting Test

Journal of Structural Engineering, 2003
The widely used concrete tensile strength test, the Brazilian cylinder splitting test, is analyzed using isoparametric nonlinear finite strip elements. The results of the numerical analysis suggest that the apparent tensile strength obtained from the splitting test underestimates the uniaxial tensile strength of concrete.

Uniaxial Tensile Testing

2004
Abstract This chapter discusses the methodology of the tensile test and the effect of some of the variables on the tensile properties. The methodology and variables discussed are shape of the item being tested, method of gripping the item, method of applying the force, determination of strength properties other than the maximum force ...

Characterization of high-temperature fatigue by the uniaxial tensile test

Journal of Materials Processing Technology, 1996
Abstract The fatigue process is a process during which the material strain-hardens under unchanged ultimate tensile strength, the fatigue deformation accumulates and the value of Young's modulus decreases. Creep process is a process during which the ultimate tensile strength decreases to the creep stress, the creep deformation accumulates and the ...

On the relevance of uniaxial tensile testing of urogynecological prostheses: the effect of displacement rate

International Urogynecology Journal, 2012
Uniaxial tensile testing is commonly used to calculate values of mechanical properties of urogynecological prostheses used in stress urinary incontinence and pelvic organ prolapse surgery in women. Clinical behavior of these products has been linked to their mechanical properties, hence influencing the clinician's preference for one brand or another ...

A STUDY OF THE SECONDARY FLEXURE IN UNIAXIAL TENSILE TEST OF CONCRETE

1999
There are three difficulties associated with carrying out uniaxial tensile tests. These are prevention of an unstable fracture, a secondary flexure and duplicate cracks. To overcome these problems, a novel technique, which consists of applying notches and attaching an adjusting gear system, is examined in this paper.

Work hardening of the material at the uniaxial tensile test

2001
The description of work hardening relationship (σ stress -e strain) through mathematical function (e.g. formulae 2.1. or 2.7.) allows to define the course of homogeneous deformation in the range where constant and unchanging deformation mechanism is active.

Uniaxial compression tests and the validity of indirect tensile strength

Journal of Materials Science, 1990
So-called “indirect” tensile tests have been adopted for various reasons, especially ease of execution and supposed freedom from several notable interferences. The extensive literature reveals much disparity in the conditions for such tests, and no consensus conclusion concerning the optimum protocol or even the interpretation of the results.

Relationships between microstructure and behaviour in the uniaxial tensile test

Journal of Physics D: Applied Physics, 1974
The present understanding of the influence of structural variables on the tensile flow strength and work-hardening behaviour of cubic metals is outlined in terms of the separate effects of crystal structure and orientation, stacking-fault energy, grain size, solution hardening, and dispersed-particle strengthening.

Tensile characteristics and behavior of blood vessels from human brain in uniaxial tensile test

KSME International Journal, 2003
The rupture of blood vessels in the human brain results in serious pathological and medical problems. In particular, brain hemorrhage and hematomas resulting from impact to the head are a major cause of death. As such, investigating the tensile behavior and rupture of blood vessels in the brain is very important from a medical point of view.
