Download or read book Application of Micromechanical Models to the Analysis of Ductile Fracture Under Dynamic Loading written by W. Böhme and published by . This book was released on 1995 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic tensile tests and instrumented impact tests with Charpy-V-notch specimens and precracked Charpy specimens (SENB) are performed and simulated. Two strain-rate dependent micromechanical models based on the modified Gurson flow function are compared by simulating different dynamically loaded specimens. One purpose of the study is to investigate the influence of strain rate on the parameters of the micromechanical models and thus to check the applicability of these models for dynamic loading. Another purpose is to find out the relation between the micromechanical approach and conventional fracture mechanics.
