Tensile Test

소개글

Tensile test is generally test that materials were drawn by regularity velocity and Load for measuring mechanical property of materials. For ductile materials, it can be got the stress-strain curve during tension test. Carbon steel may be shown the yield point phenomenon. Al6061 is typically shown as ductile behavior. Polycarbonate can be observed the distinctive necking behavior. Each material has three specimens. One is the controlled specimen, another is heat treated specimen, and the other is fast specimen in cross-head velocity. We can obtain the Load-displacement curves by the each variable. The Load-displacement curve should be converted the stress-strain curve by using chart speed, crosshead speed, and initial length. Also Young`s modulus, yield strength, and tensile strength can be calculated by stress strain curve. And, we consider what to be mechanical property of materials.

Abstract
Tensile test is generally test that materials were drawn by regularity velocity and Load for measuring mechanical property of materials. For ductile materials, it can be got the stress-strain curve during tension test. Carbon steel may be shown the yield point phenomenon. Al6061 is typically shown as ductile behavior. Polycarbonate can be observed the distinctive necking behavior. Each material has three specimens. One is the controlled specimen, another is heat treated specimen, and the other is fast specimen in cross-head velocity. We can obtain the Load-displacement curves by the each variable. The Load-displacement curve should be converted the stress-strain curve by using chart speed, crosshead speed, and initial length. Also Young`s modulus, yield strength, and tensile strength can be calculated by stress strain curve. And, we consider what to be mechanical property of materials.
