Damage and smeared crack models

WebDec 31, 2008 · Complexity of failure is reflected from sensitivity of strength to small defects and wide scatter of macroscopic behaviors. In engineering practices, spatial information of materials at fine scales can only be partially measurable. Random field (RF) models are important to address the uncertainty in spatial distribution. To transform a RF of micro … WebApr 11, 2024 · Many available constitutive models exist in ABAQUS CAE software, two of the models usually used are concrete-smeared cracks [19] and concrete-damaged plasticity (CDP) [20]. These two constitutive models necessitate extensive material property parameters and coefficients, such as compression/tension plastic stress-strain datasets, …
