Tensile elongation maximum

Observations of what appeared to be superplastic behavior were initially made in the late 1920s with a maximum of 361% for the Cd-Zn eutectic at 20°C and strain rates of 10 /s and 405% at 120°C and a strain rate of 10 /s. Jenkins [2] also reported a maximum of 410% for the Pb-Sn eutectic at room temperature but at strain rates of 10 /s. However, the most spectacular of the earlier observations was that by Pearson in 1934 [3]. While working on eutectics, he reported a tensile elongation of 1950% without failure for a Bi-Sn alloy.

All the unfilled vulcanizates based on linear a,co-DHPS are distinguished by a tensile strength maximum of 1 kg/cm and a percentage elongation at rupture of 80 - 120%. 

The blends were prepared in a twin-screw extruder. The spiral flow was determined at a melt temperature of 288°C (550°F) for the PC and 266°C (510°F) for the transparent DB. The mold release energy was determined by measuring the force required to eject a disc measuring 76 mm in diameter and 3.2 mm thick with 6.4 mm high ribs. The chemical resistance was determined by measuring the maximum allowable outer fiber strain on 2.0 mm tensile bars, which did not reduce tensile elongation. 

Same material but containing 0.1% of a photostabilizer (Cyasorb UV 3346, American Cyanamid Co.) was also studied in a similar experiment designed to obtain a direct activation spectrum of the material [133]. After 1400 h exposure in an Atlas Ci 65 weatherometer, the samples showed measurable changes in both elongation at break as well as the tensile strength. Maximum effectiveness was found at A = 335-355 nm. 

Physical Properties The usual values of tensile strength, tensile modulus, and ultimate elongation at various temperatures can be obtained from the typical stress-strain curves shown in Figs. 22-01 and 22-02. Such properties as tensile strength and modulus are inversely proportional to temperature, whereas elongation reaches a maximum value at about 300°C. Other factors, such as humidity, film thickness, and tensile elongation rates, were found...

Polyphase Alloys. The two-phase alloys have a rather wide range of properties resulting from variations within the stmcture. If the second phase is distributed in critical depression, the hardness and strength are at a maximum and the ductility is at a moderate level. Tensile strength may be 415—825 MPa (60,000—120,000 psi) yield strength, 170—585 MPa (25,000—85,000 psi) and elongation, 10—40%. 

GPa) and the relative elongation at break (%). The first of the indices characterizes the resistance of the fiber to deformation under the affect of the acting force and determines the value of the tensile strength causing the formation of the unitary relative elongation (e). The modulus E characterizes the susceptibility of the fiber to deform based on the principle of inverse proportionality. The other parameter, i.e., 6, characterizes the maximum ability of the fiber to deform under the effect of the acting tensile force. 

Aluminum drillpipe is generally made of 2014 type aluminum-copper alloy. Composition of this alloy is 0.50 to 1.20% silicon, 1.00% iron maximum, 3.90 to 5.0% copper, 0.40 to 1.20% manganese, 0.25% zinc maximum and 0.05% titanium. The alloy is heat treated to T6 conditions that represent 64 ksi tensile strength, 58 Ksi yield strength, 7% elongation and a Hbn of 135- Aluminum drillpipe generally comes with steel tool joints that are threaded on to ensure maximum strength that cannot be attained with aluminum joints. 

The maximum in the curve denotes the stress at yield av and the elongation at yield v. The end of the curve denotes the failure of the material, which is characterized by the tensile strength a and the ultimate strain or elon gation to break. These values are determined from a stress-strain curve while the actual experimental values are generally reported as load-deformation curves. Thus (he experimental curves require a transformation of scales to obtain the desired stress-strain curves. This is accomplished by the following definitions. For tensile tests ... 

Young s modulus may be calculated from the flexure of other kinds of beams. Examples are given in Table 1 (11,12). The table also gives equations for calculating the maximum tensile stress am ix and the maximum elongation en,.,x, which are found on the surface at the center of the span for beams with two supports and at the point of support for cantilever...
