• The evaluation of fracture toughness is very important when we predict ultimate strength of material. The standard testing method for fracture toughness evaluation is already proposed. However, making an experiment using the standard test method is a little complicated including production of a loading apparatus. In this study, fracture toughness K_<IC> is estimated by some easy testing methods using the model that can evaluate a stress intensity factor K_1. The acryl resin specimen that shows a linear behavior is used for the experiment, and K_<IC> is evaluated using the maximum load. The error over each testing method is investigated, and the strong and weak point for each procedure is discussed.
