This study aims to analyze the effects of variations in stainless steel material types (SS 316L, SS 301, SS 304, and S17400/17-4 PH) and thicknesses (6.35 mm, 9.525 mm, and 12.7 mm) on the cracking risk of pressure vessels, as well as to determine the optimal material and thickness combination to minimize cracking potential using the Finite Element Method (FEM). The research was conducted through numerical simulations using ANSYS Mechanical software, employing a Compact Tension model based on ASTM E399 standards. The analyzed parameters included normal stress (σx, σy, σz), directional deformation (dx, dy, dz), crack characteristics, and Stress Intensity Factor (SIFs K1). Simulations were performed by applying proportional tensile loads for each thickness (3000 N for 6.35 mm, 4500 N for 9.525 mm, and 6000 N for 12.7 mm). Simulation results on mechanical crack resistance indicate that the combination of SS 301 material with a thickness of 12.7 mm is the most optimal choice for preventing cracking in pressure vessels. SS 301 offers superior resistance to crack propagation due to its high modulus of elasticity and low deformation. Meanwhile, the 12.7 mm thickness effectively distributes loads, reducing stress, crack length, and crack growth rate. date: 2025-07-24 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/52695/1/Akmal%20Mahfuzh%20Mushoddaq_3331210004_Fulltext.pdf format: text language: id identifier: https://eprints.untirta.ac.id/52695/2/Akmal%20Mahfuzh%20Mushoddaq_3331210004_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/52695/3/Akmal%20Mahfuzh%20Mushoddaq_3331210004_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/52695/4/Akmal%20Mahfuzh%20Mushoddaq_3331210004_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/52695/5/Akmal%20Mahfuzh%20Mushoddaq_3331210004_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/52695/6/Akmal%20Mahfuzh%20Mushoddaq_3331210004_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/52695/7/Akmal%20Mahfuzh%20Mushoddaq_3331210004_Ref.pdf format: text language: id identifier: https://eprints.untirta.ac.id/52695/8/Akmal%20Mahfuzh%20Mushoddaq_3331210004_Lamp.pdf format: text language: id identifier: https://eprints.untirta.ac.id/52695/9/Akmal%20Mahfuzh%20Mushoddaq_3331210004_CP..pdf identifier: Mushoddaq, Akmal (2025) ANALISIS KERETAKAN PADA MATERIAL PRESSURE VESSEL STAINLESS STEEL MENGGUNAKAN FINITE ELEMENT METHOD (FEM).
