A Non-Intrusive Fluorescent Pattern for Internal Microscale Strain Measurements Using Digital Image Correlation

February 1, 2023
Author(s)
Ami Ahure Powell, William Mulhearn, Shawn Chen, Stephan J. Stranick, Jeffrey Gilman, Mark Iadicola, Jeremiah Woodcock
A non-intrusive and non-disruptive internal fluorescent pattern is designed, developed, and tested using digital image correlation (DIC), an effective non-contact optical method, to measure deformation at internal planes of a polymer matrix material. The

Double Interpolation to Achieve Linear Strain Path for AISI 1008 Steel Cruciform Specimen

September 30, 2022
Author(s)
Jordan Hoffman, Jinjin Ha, Brad Kinsey, Mark Iadicola, Dilip K. Banerjee
The automotive industry relies heavily on sheet metal forming processes for many components. Material data solely from uniaxial testing is insufficient to fully define the material behavior of the complex plastic deformation during numerical simulations of

Plastic Anisotropy Evolution of SS316L and Modeling for Cruciform Specimen

August 20, 2022
Author(s)
Dilip K. Banerjee, Elizabeth Mamros, Sarah Mayer, Mark Iadicola, Brad Kinsey, Jinjin Ha
In this paper, the evolution of the plastic anisotropy of stainless steel 316L samples is investigated under proportional loading paths using a customized cruciform specimen. The determination of a novel cruciform specimen by a design of experiments

Evaluation of Methods for Determining the Yoshida-Uemori Combined Isotropic/Kinematic Hardening Model Parameters from Tension-Compression Tests of Advanced Lightweighting Materials

August 19, 2022
Author(s)
Dilip K. Banerjee, William E. Luecke, Mark Iadicola, Evan Rust
The performance of two methods, termed Manual and Optimization, for determining the values of the constitutive-model parameters for Yoshida-Uemori (Y U) isotropic-kinematic hardening model was evaluated. The Y U parameters were determined for two 6000

2020 Numisheet benchmark study tension/compression test summary

April 28, 2022
Author(s)
William E. Luecke, Evan Rust, Mark Iadicola
This report describes the test equipment, process, analysis, and data-file formats for the tension/compression testing of the four materials associated with the Numisheet conference Benchmarks. The four materials include two steels alloys, DP980 for

DIC Challenge 2.0: Developing Images and Guidelines for Evaluating Accuracy and Resolution of 2D Analyses: Focus on the Metrological Efficiency Indicator

January 4, 2022

Philip Reu, EMC Jones, S.S. Fayad, B. Blaysat, E. Toussaint, Mark Iadicola, P. Lava, J Rethore, J. Yang, K. Bhattacharya, L. Yang, D. Deb, C.S.R. Vemulapati, M Klein, E Ando, E Roubin, O. Stamati, C Couture, Alexander Landauer, M. Liu, S Jaminion, T. Siebert, S.N. Olufsen
Background The DIC Challenge 2.0 follows on from the work accomplished in the first Digital Image Correlation (DIC) Challenge Reu et al. (Experimental Mechanics 58(7):1067, 1). The second challenge was required to better quantify the spatial resolution of

Influence of Drawbeads in Deep Drawing of Plane-Strain Channel Sections

October 12, 2021
Author(s)
D E. Green, T B. Stoughton, Thomas H. Gnaupel-Herold, Mark Iadicola, Timothy J. Foecke
The Numisheet 2005 Benchmark 3 consisted of forming four different automotive sheet materials in a two-stage process. The first stage consisted of forming channel sections in an industrial-scale channel draw die in which material flow is controlled by

Two Stage Forming: Experimental and FE Analysis

M C. Oliveira, A J. Baptista, J L. Alves, L F. Menezes, D E. Green, Thomas H. Gnaupel-Herold, Mark Iadicola, Timothy J. Foecke, T B. Stoughton
One of the present challenges in sheet metal forming is to simulate sequential production stages, from the initial blank sheet to the final part ready for assembly. In this context, it is fundamental to evaluate the forming characteristics of the materials

2020 Numisheet benchmark study uniaxial tensile tests summary

April 29, 2020
Author(s)
Evan Rust, William E. Luecke, Mark Iadicola
This report describes the test equipment, process, analysis, and data file formats for the 2020 Numisheet benchmark study tensile testing of the four materials associated with the Numisheet conference benchmarks. The four materials include two steel alloys

Insights into Cruciform Sample Design

January 30, 2017
Author(s)
Adam A. Creuziger, Mark A. Iadicola, Timothy J. Foecke, Evan Rust, Dilip K. Banerjee
Four different cruciform sample designs, based on the work of Abu-Farha et al, were studied in this paper. The original design of Abu-Farha was validated at room temperature for a thicker sample, and two modified sample geometries that would permit thinner

Crystal Plasticity Analysis of Constitutive Behavior of 5754 Aluminum Sheet

June 30, 2016
Author(s)
Minh-Son Pham, Anthony D. Rollett, Adam Abel Creuziger, Mark Iadicola, Timothy J. Foecke
Crystal plasticity constitutive equations for the multi-axial stress-strain behavior of aluminum alloy 5754 sheets have been developed. A Taylor model, a self-consistent visco-plastic model and an N-site model based on the Fast Fourier Transform were used

June 6, 2016
Author(s)
Mark A. Iadicola, Dilip K. Banerjee, Adam A. Creuziger
Multi-axial specimen geometry optimization through finite element analysis requires robust models that incorporate the critical physics of the experiment as well as a sufficiently robust constitutive law. This can be difficult even at low nominal strain
