Uniaxial tensile stress rupture testing of hot-pressed silicon nitride NC-132 was carried out at 1000°, 1200°, and 1300°C in air at various applied stress levels and the corresponding times-to-failure were measured. Fracture occurred from both surface and internally initiated flaws. Fracto...

The flexural strength is related to the specified design compressive strength by the equation below. (Ferron, 2014) This equation can be altered to determine if the measured flexur...
12.6). For unbonded tendons, although the stress also jumps from point Cu to point Du, the change is relatively smaller since the longitudinal deformation due to cracks is almost evenly distributed over the entire length. At rupture, the stress in bonded tendons reaches the ultimate tensile ...
The flexural properties of compression molded stampable glass fiber reinforced polypropylene are examined. Fibers flowing with the polymeric matrix are found to be oriented close to the edge of the die. The fiber orientation distribution is characterized by a fiber orientation index using an image pro...
In particular, flexural loading is more commonly encountered than uniaxial tensile loading. Flexure is more complicated than uniaxial tension in that the strain/stress is non-uniform. Under flexure, one surface is under compression while the opposite surface is under tension. As a result, the ...
The values are significantly different from the tensile modulus. This is because the stress pattern in the specimen is a combination of tension and compression. The data is useful for comparing the strength and stiffness of different plastics. ...
bilinear stress-total strain constitutive behavior with strain hardening considering: tensile strength (fst) of 500 MPa, ultimate tensile strength (fstu) of 550 MPa, elastic strain (εst,el) of 0.0025, ultimate tensile strain (εst,u) of 0.05 and elastic modulus (Es) of 200,000 MPa...
