This study was aimed to analyze and compare the strength of tensile test specimens with geometrical alterations. In this study, the Type I standard test specimen created according to the ASTM D638-14 standard was used. Then, geometric alterations were made on this standard test specimen. All specimens were created by Autodesk Inventor modeling software and analyzed and simulated with "Static Structural Method in CAE (Computer Aided Engineering) software" by defining Polylactic Acid (PLA) material. Results of geometrical alterations, five different kinds of test specimen were developed. Alterations were S-1, slotting in the middle of the test specimen; S-2, drilling two holes of same diameters to the test specimen at equal intervals; S-3, adding radii to the corners of the test specimen; S-4, enhancing the thickness of the test specimen and S-5, adding two cam slots to the test specimen at equal intervals, respectively. As a result of each theoretical specimen´s data from simulations, the tensile strengths of the specimens were compared and their maximum deformations.
