Abstract We formulate a Data Driven Computing paradigm, termed max-ent Data Driven Computing, that generalizes distance-minimizing Data Driven Computing and is robust with …
T Kirchdoerfer, M Ortiz - International Journal for Numerical …, 2018 - Wiley Online Library
We formulate extensions to data‐riven computing for both distance‐minimizing and entropy‐ maximizing schemes to incorporate time integration. Previous works focused on formulating …
This paper reports the advantages and limitations of the digital image correlation (DIC)- based non-contact measurement technique through full-scale testing of prestressed …
The calibration of phenomenological constitutive material models has been a constant need, because the parameters differ for each material and the ability of a model to mimic the real …
The use of experimental tests that involve full‐field measurements to characterize mechanical material properties is becoming more widespread within the engineering …
In this paper, we address the effective and robust identification of material behavior parameters from full-field measurements obtained by means of the advanced Digital Image …
