1 Fracture problems with ANSYS A (very) brief introduction Introduction and objective ANSYS is a commercial finite element code used in industry to solve large scale problems. It can be used to solve a wide variety of problems including linear and nonlinear structural response, buckling, modal analysis, full harmonic response, transient dynamic response, heat transfer, electro-magnetic and fluid flow problems. ANSYS offers a large library of elements ranging from the simplest (1-D elastic bar element) to the very complicated (3-D nonlinear elasto-plastic element). Information about these elements and the type of analysis available in ANSYS can be found in various sources and manuals. Help is also available interactively within ANSYS. The objective of this short exercise is to extract the value of the stres intensity factor for a compact tension test (CT) linearly elastic specimen described in Section A4 of the E 3999 ASTM Standard (se first two pages of the A...
