Group 2 Tuesday 11 AM. Tensile Test Lab Report Name of student. TENSILE TEST G ROUP ONE D AVID B ROWNE 851594 OBJECTIVES The objective of this experiment is to investigate the behavior of two material specimens under a Tensile Test.
If one pulls on a material until it breaks one can find out lots of information about the various strengths and mechanical behaviors of a material. The 02 offset line was roughly 9 MPa the modulus of elasticity was 268 MPa and the elongation was 21224. Its ultimate tensile strength was 385MPa youngs modulus of 96000 MPa and yield stress of 340 MPa.

4 is used for tensile testing of specimens. The report should contain 4 Figures graphs that contain an overlay of engineering and true stress-strain. Universal Testing Machine is used to conduct the Tensile Test.
The Universal Testing Machine can be used to determine the tensile strengths of many. Analysis and report of stress strain and other computed material characteristics. In this test a standard plain concrete beam is subjected to two-point loading also called four-point loading or third point loading.
Load controlled machine 2. Convenient sample geometry for the tensile test is the dogbone geometry Figure 1. The basics on the operation of universal testing machine were also learnt during this experiment.
The tensile test experiment can be used to determine other mechanical characteristics of the specimen like yield strength percentage elongation and ultimate strength among others. The topic of this lab is confined to the tensile property of polymers. Tensile testing is one of the simplest and most widely used mechanical tests.
Do mm Lo mm Df mm Lf mm Youngs modulus GPa Ultimate Strength N. The tensile load and corresponding extensions are then recorded for calculations and determination of stress-strain relationship of the material specimen. In this paper the author is reporting values as mean value - standard deviation of the data.
