Consideration of Stress-Strain Relation (Report 1)

Modeling of Tensile Stress-strain Relation of Pseudo Strain Hardening Cementitious Composites

This study proposes a new comprehensive theoretical approach for predicting tensile stress-strain relation of Random Short Fiber Reinforced Cement Composites (RSFRCC) showing Pseudo Strain Hardening (PSH). This approach is grounded on solid basis of micromechanics, which describes PSH phenomenon in terms of constitutive properties of fiber, matrix, and fiber/matrix interface. The proposed model...

A New Technique based on Strain Energy for Correction of Stress-strain Curve

Tensile stress-strain curve is of high importance in mechanics of materials particularly in numerical simulations of material deformations. The curve is usually obtained by experiment but is limited by necking phenomenon. Engineering stress-strain curve is converted to true stress-strain curve through simple formulas. The conversion, however, is correct up the point of necking. From this point ...

Stress-Strain Field and Theoretical Analysis of RC Bridge

In this paper, a reinforced concrete(RC) bridge built in an interchange, in the city of Kerman (a city located in south of Iran) is examined by the Structural Health Monitoring (SHM) system. During the construction of this bridge such as; the main beams, slab, and retaining walls, some Electrical Strain Gauges were mounted on the main reinforcements at different locations within the body of thi...

Characteristic Points of Stress-Strain Curve at High Temperature

Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...
