| Abstract | This paper aims to explore the built-in failure criteria functions provided by ANSYS to simulate the failure behaviour of composite plates under tension. The first ply failure (FPF) load is determined and the results are used for the time to assess the accuracy of the available built-in failure criteria. Finite element (FE) models are developed using standard ANSYS formulation to replicate physical uni-axial tensile tests. The built-in failure criteria functions are explored and the available criteria (Maximum Stress and Tsai-Wu Failure Criteria) are used to determine the FPF load for a composite laminate, with a layup of (θ4/04/− θ4)s. The angle, θ, is varied from 0° to 90°. The results are compared with a (FE) implementation using Fortran and available experiment data. The FPF curves for both ANSYS and Fortran were plotted and found very close to the experiment results. By comparing the curves, the results are used to assess and evaluate the accuracy of the failure criteria. The results show that the current ANSYS and Fortran simulations produce a maximum average error of 16%. Using ANSYS, the Maximum Stress and Tsai-Wu criteria produce an average error of 5.78%, and 13.19% respectively. Using Fortran programme, Maximum Stress produces an average error of 1.36%. Despite larger error, simulations using ANSYS allows easier modification and manipulation. Moreover, the procedure of simulations has the potential to replace tedious and expensive physical testing. Therefore, it can be concluded the current study has successfully explored the built-in failure criteria functions in ANSYS to replicate experiments. Apparently, the current study is novel, useful and contributes significant knowledge in conducting failure analysis of composite laminates. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
