In this research, the artificial neural network (ANN) approach was investigated for predicting strain gauge results of unidirectional laminated composites' tensile tests. This approach involves training an ANN with a dataset of known strain gauge readings and their corresponding tensile test results. The required data to train the network was generated by using 15 different tensile test data created by MTS series 322 test frame. Strain values of MTS device were used as an input in ANN formation to estimate strain gauge results. The dataset was rearranged by applying normalization and linearization processes. Strain results were predicted approximately above 99% accuracy. In conclusion, a highly trained ANN system is a reasonable approach to approximate strain gauge results from MTS device test results. As a future goal the well-trained ANN system can be the option for obtaining materials stress-strain curves without testing by using machine learning and deep learning algorithms.
