a. b. C. d. Based on the 2nd case study you have selected for your coursework describe briefly the process you followed to ensure that the finite element model you developed is representative of the specimen you have considered. Describe the iterative solution procedure adopted by the finite element package you have employed for investigating numerically the nonlinear behaviour of the structural form you have selected for the 2nd case study of your coursework. Discuss the accuracy of the numerical predictions obtained while also providing a brief description of the behaviour exhibited by the specimen up to failure. Base your discussion around (a) the Load-deflection curves; (b) the crack patterns developing along the span of the specimen at different stages of the loading process and (c) the mode of failure exhibited by the specimen. Discuss the reasons of any divergence between the numerical predictions and the test data. If you were given the opportunity to repeat this study what would you have done differently? M40 morkel
