Grain boundary sliding and non-constancy strain during stress relaxation of pure Mg

June 10, 2021

Author(s)

Dilip K. Banerjee, Anand Varma, Aditya Gokhale, Jayant Jain, Krishnaswamy Hariharan

Stress relaxation during plastic deformation has been reported to improve ductility of metallic materials. In this study, the stress relaxation behavior in pure magnesium is investigated during interrupted uniaxial tensile tests. During intermittent

On the interplay of friction and stress relaxation to improve stretch-flangeability of dual phase (DP600) steel

January 6, 2021

Author(s)

Dilip K. Banerjee, Kali Prasad, Krishnaswamy Hariharan, Uday Chakkingal

Industrial servo press has successfully demonstrated improved formability when deforming sheet metals. While the time dependent viscous behaviour of material is attributed to the observed formability improvement, much less efforts have been devoted to

Thermal response of a composite floor system to the standard fire exposure

December 1, 2019

Author(s)

Dilip K. Banerjee

This paper discusses the development of a finite element model (FEA) of a full-scale composite floor system and application of this model to predict the heating of steel members when exposed to a standard fire during fire resistance experiments. The model

A Design of Experiments Approach for Determining Sensitivities of Forming Limit Analyses to Experimental Parameters

October 2, 2018

Author(s)

Mark A. Iadicola, Dilip K. Banerjee

Forming limit testing is widely used to characterize materials for use in forming operations. Subset based Digital Image Correlation (DIC) has become a common method used in research laboratories to measure the forming limit strain fields, but no

Simulation of temperature, stress and microstructure fields during laser deposition of Ti-6Al-4V

September 25, 2018

Author(s)

Supriyo Ghosh, Kevin S. McReynolds, Jonathan E. Guyer, Dilip K. Banerjee

We study the evolution of prior columnar β phase, interface L phase, and α phase during directional solidification of a Ti-6Al-4V melt pool. Finite element simulations estimate the solidification temperature and velocity fields in the melt pool and analyze

Toward Development of Optimum Specimen Designs and Modeling of In-plane Uniaxial Compression Testing of Aluminum alloy 2024 and AISI 1008 Steel Sheet Material

July 1, 2018

Author(s)

Dilip K. Banerjee, Mark A. Iadicola, William E. Luecke, Timothy J. Foecke, Christopher A. Calhoun

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

A comparison of strain calculation using digital image correlation and finite element software

September 4, 2016

Author(s)

Dilip K. Banerjee, Mark Iadicola

Digital image correlation (DIC) data are being extensively used for many forming applications including constitutive law calibration, benchmark calibration, and for comparisons with finite element analysis (FEA) simulated results. The most challenging

FEA parameter verification for strain localization experiments

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

An analytical approach for estimating uncertainty in measured temperatures of concrete slab during fire

March 26, 2016

Author(s)

Dilip K. Banerjee

To evaluate the fire resistance of concrete slabs used in composite floor systems, the temporal and spatial variation of measured temperatures must be accurately determined. Temperature profiles in a concrete section are a function of concrete

Mechanical properties of single-walled carbon nanotube reinforced polymer composites with varied interphases modulus and thickness: A finite element analysis study

January 8, 2016

Author(s)

Dilip K. Banerjee, Tinh Nguyen, Tze-Jer Chuang

The role of the interphase on mechanical performance of glassy polymer/single-walled carbon nanotube composites has been investigated by finite element (FE) method. The matrix and the interphase are modeled using continuum elements and the nanotube is

Finite Element Modeling of Deformation Behavior of Steel Specimens under Various Loading Scenarios

July 15, 2015

Author(s)

Dilip K. Banerjee, Mark A. Iadicola, Adam A. Creuziger, Timothy J. Foecke

Lightweighting materials (e.g., advanced high strength steels, aluminum alloys etc.) are increasingly being used by automotive companies as sheet metal components. However, accurate material models are needed for wider adoption. These constitutive material
