Question

The material for the 55-mm-long specimen has the stress-strain diagram shown. If P=150kN is applied and then released, determine the permanent elongation of the specimen. Provide calculations and results based on the given information.

Answer 1

To determine the permanent elongation of the specimen, the stress-strain diagram is required.

Step-by-step explanation:

To determine the permanent elongation of the specimen, we need to find the area under the stress-strain curve up to a stress of 150 kN/m² (since P=150 kN). The permanent elongation corresponds to the strain at this stress level. However, since the stress-strain diagram is not provided, we cannot perform the calculations or provide a precise answer.
