A tensile test was performed on a metal specimen having a circular cross section with a diameter of 1 2 inch. The gage length (the length over which the elongation is measured) is 2 inches. For a load 13.5 kips, the elongation was 4.6610 3 inches. If the load is assumed to be within the linear elastic rang: of the material, determine the modulus of elasticity.

A tensile test was performed on a metal specimen having a circular cross section with a diameter 0. 510 inch. For each increment of load applied, the strain was directly determined by means of a strain gage attached to the specimen. The results are, shown in Table: 1.5.1. a. Prepare a table of stress and strain. b. Plot these data to obtain a stress-strain curve. Do not connect the data points; draw a best-fit straight line through them. c.

A compact tension specimen is tested according to ASTM standard E399. The load displacement curve is shown in the Figure below with PQ= 120 kN (Type 1 curve). The specimen dimensions are B=0.5 cm, W=10 cm, and “a” =5 cm. If the materials yield stress is 600 MPa are the conditions correct for a valid K1C measurement?
