Tensile Strength Report | Materials in Practice CP4088/CP8011 | By Clinton Chang | Synopsis This experiment is to find out the tensile strength of different plastic materials. The four plastic materials used are General Purpose Polystyrene (GPPS)‚ High Impact Polystyrene (HIPS)‚ High Density Polyethylene (HDPE) and Polypropylene (PP). By using three samples from each plastic material type‚ we are able to obtain the mean tensile strength‚ mean tensile modulus and mean yield strength of each

cross-sectional area of 0.25 in2 is stretched between two fixed points. The tensile load at 70°F is 1200 lb. What will be the stress at 0°F? At what temperature will the stress be zero? Assume α = 6.5 × 10-6 in/(in·°F) and E = 29 × 106 psi. Solution 261 For the stress at 0°C: answer For the temperature that causes zero stress: answer problem 262 A steel rod is stretched between two rigid walls and carries a tensile load of 5000 N at 20°C. If the allowable stress is not to exceed 130

Materials Laboratory 4: Compressive‚ Flexural‚ and Tensile Strength of Concrete Lab Section: TH 2–5 PM Unique #: 15785 Lab TA: Janaki Vamaraju Solutions: 1.) In this lab‚ concrete cylinders and beams created from Lab 3 were tested for compressive‚ flexural‚ and tensile strength. The compressive strength of the concrete was found by applying an axial load on the cylinder until the cylinder failed. The flexural strength was calculated by subjecting transverse loads at the

measure the mechanical properties of a material is the Tension Test. Tension test is widely used to provide a basic design information on the strength of materials and is an acceptance test for the specification of materials. The major parameters that describe the stress-strain curve obtained during the tension test are the tensile strength (UTS)‚ yield strength or yield point (σy)‚ elastic modulus (E)‚ percent elongation (∆L%) and the reduction in area (RA%). Toughness‚ Resilience‚ Poisson’s ratio(ν)

Tensile Testing Of Metallic Materials 概要： Tensile testing of metallic materials is specified according to European EN 10002 standard. In this article the terms‚ definitions and designation for tensile test made at ambient temperature is described. The test involves straining a test piece in tension‚ generally to fracture‚ for the purpose of determining mechanical properties. Tensile testing of metallic materials is specified according to European EN 10002 standard. This standards consists of five

Abstract A tensile test was conducted on an Instron tensile machine using a 3/16 inch copper rod. Using data acquired stress and strain was calculated and plotted on Excel to analyze stress strain curve. Modulus of elasticity‚ 0.2% yield stress‚ ultimate tensile stress and % elongation were also calculated. Introduction A tension test is probably the most fundamental type of mechanical test you can perform on material. Tensile tests are simple‚ relatively inexpensive‚ and fully standardized
