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

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

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

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

Solidification

December 19, 2014
Author(s)
William J. Boettinger, Dilip K. Banerjee
In this chapter, we give a general view of the formation of the solid from its melt. This process is generally driven by the extraction of heat from the melt but fluid flow has a major influence on solidification. Thus an early section deals with transport

Software Independent Data Mapping Tool for Structural Fire Analysis

March 12, 2014
Author(s)
Dilip K. Banerjee
In order to model the structural behavior under fire, three separate analyses need to be conducted: a) fire propagation and growth (fire modeling), b) transient heat transfer in structural members due to fire, and c) structural analysis to account for both

Practical CFD Simulations of Wind Tunnel Tests

December 1, 2013
Author(s)
Dilip K. Banerjee, Scott Hemley, Randall J. McDermott, Donghun Yeo, Marc L. Levitan
Computational fluid dynamics (CFD) has the potential of replacing wind tunnel testing in many wind engineering applications. Validated CFD software could enable structural engineers and builders to calculate wind effects on buildings for which no

Uncertainties in Steel Temperatures during Fire

August 4, 2013
Author(s)
Dilip K. Banerjee
In order to determine the fire resistance of steel members, steel temperatures must be estimated with a high confidence. There can be considerable uncertainty in temperatures of both protected and unprotected steels during fire exposure. This is due to

NIST ADVANCES IN COMPUTER-AIDED AND COMPUTATIONAL METHODS IN WIND ENGINEERING

October 19, 2012
Author(s)
Dong Hun Yeo, Franklin T. Lombardo, Dilip K. Banerjee, Eric J. Letvin, Emil Simiu, Marc L. Levitan, Florian A. Potra
The paper summarizes recent research and development of computer-aided and computational methods in wind engineering at the National Institute of Standards and Technology (NIST). Specific topics to be covered include: 1. Time-domain database-assisted
