A STUDY ON ELASTO-PLASTIC BEHAVIOR AND FRACTURE CHARACTERISTICS OF NOTCHED PLATE TENSILE SPECIMEN
Elasto-plastic behavior for both center notched and side notched plate specimens were studied as a first step toward prediction of fracture. Elasto-plastic analysis by finite element method and brittle coating were used to approach the problem. At each stress level, brittle coating cracks formed at high strain range showing contours of equal strain were in good agreement with the predicted shape using the finite element method. Fracture test results on both center notched and side notched specimens were compared. And they were discussed on the basis of elasto-plastic analysis. From examination of the properties of matrices, it was made clear that a computed result for a given condition of a specimen can directly be applied to obtain a solution in a different state if (i) geometric similarity exists in specimens; (ii) the Young's modulus and strain hardening coefficient are varied while the ratio between the two is kept constant; (iii) yield stress is varied in specimens.
