20.500.12556/RUL-167651 Inverse calibration of out-of-plane shear anisotropy parameters of sheet metal The accurate description of sheet metal forming processes such as blanking, riveting, incremental forming, and ironing strongly depends on understanding the material’s through-thickness shear resistance and plastic behavior. A three-dimensional model of plastic anisotropy is required to capture this behavior, but calibrating the out-of-plane shear parameters is often challenging. Researchers frequently assume isotropy or set the in-plane and out-of-plane shear parameters equal. More advanced approaches use a crystal plasticity model, which also requires calibration based on available material texture data. In this work, we introduce an out-of-plane shear test procedure that combines a macromechanical test with digital image correlation to inversely calibrate the shear anisotropy parameters of the YLD2004-18p yield function. This method efficiently characterizes both in- plane and out-of-plane shear anisotropy in medium-thick sheet metals. plastic anisotropy shear testing YLD2004–18p yield function material identification digital image correlation plastična anizotropija strižno testiranje YLD2004–18p funkcija tečenja materialna identifikacija metoda korelacije digitalnih slik true false false Angleški jezik Slovenski jezik Neznano 2025-03-05 12:14:26 2025-03-05 12:14:31 2025-03-06 04:01:05 0000-00-00 00:00:00 2025 0 0 20 str. art. 113313 Vol. 313 May 2025 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-02-27 2027-02-27 621 1879-2146 10.1016/j.ijsolstr.2025.113313 227822851 RAZ_Starman_Bojan_2025.pdf RAZ_Starman_Bojan_2025.pdf 1 28BD9E0079A6CA6A5AFD687E8F84E1E0 6611f5a5bb1449ea5b765bbf7db4ae85c2640401dcd54b7dae99a099a0a66abc 8ac5d47c-f9b2-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200345 https://www.sciencedirect.com/science/article/pii/S002076832500099X 1 1494017f-f9b2-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200344 Fakulteta za strojništvo 0 0 0
