You can model the crack as a mathematically sharp one. You will need to use symmetry criterions if you want to generate a whole model. You can probably go through Prof. Phan's (Univ. of Southern Alabama) Ansys Tutorials to get a fair idea of what you need to do.
you wanna simulate the 2D crack in ANSYS, well if you are interested in crack propagation then you need to model the crack in pre domain and then find the stress intensity factor K-I, K-II, K-III, at the crack tip to evaluate the propagation of crack, well you can use the beam or plane element, rather you can also use the shell element, but one thing you need to modelled the singular element at the crack tip as well as the co-ordinate system to read the result in the local domain.
Hi, I am doing similar project on plates. I did analysis for static loading ( pure tension). Now I want do the same analysis with cyclic loading. Could you please tell how to apply fatigue load in a ansys?
I am currently doing a research on laminate composite crack growth using SMART Crack Growth feature in ANSYS R19.1, based on this tutorial. When I follow the tutorial there is nothing error, but when I was changed the geometry, I faced an unknown problem that stated in Messages prompt. It said:SMART remeshing algorithm does not produce new crack surface with a good quality mesh for Cgrow ID 1. Crack propagation is stopped.
Each learning module below contains a step-by-step tutorial that shows details of how to solve a selected problem using ANSYS, a popular tool for finite-element analysis (FEA). The tutorial topics are drawn from Cornell University courses, the Prantil et al textbook, student/research projects etc. If a tutorial is from a course, the relevant course number is indicated below. All tutorials have a common structure and use the same high-level steps starting with Pre-Analysis and ending with Verification and Validation . Pre-Analysis includes hand calculations to predict expected results while Verification and Validation can be thought of as a formal process for checking computer results. Both these steps are extremely important in practice though often overlooked. The pedagogical philosophy behind these modules is discussed in this article from the ANSYS Advantage magazine.
The following ANSYS tutorials focus on the interpretation and verification of FEA results (rather than on obtaining an FEA solution from scratch). The ANSYS solution files are provided as a download. We read the solution into ANSYS Mechanical and then move directly to reviewing the results critically. We are particularly interested in the comparison of FEA results with hand calculations. 2b1af7f3a8
