Experimental studies of the deformation mechanisms of core-shell rubber-modified diglycidyl ether of bisphenol-A epoxy at cryogenic temperatures

Autor: Judy Schneider, H. R. Brown, Taylor L Murphy

Publikováno v: Journal of Composite Materials. 48:1279-1296

Epoxy polymers, although often used in fiber-reinforced polymeric composites, have an inherent low toughness that further decreases with decreasing temperatures. Second-phase additives have been effective in increasing the toughness of epoxies at roo

Microstructure–property relations of a steel powder metal under varying temperatures, strain rates, and stress states

Autor: Matthew T Tucker, Mark F. Horstemeyer, Youssef Hammi, H. R. Brown, Paul G. Allison, Youngkeun Hwang

Publikováno v: Materials Science and Engineering: A. 529:335-344

This study is a first to analyze the microstructure and associated plasticity and fracture characteristics under finite deformations for quantifying different applied stress state, strain rate, and temperature effects on a porous powder metal steel (

Modulus Dependence on Large Scale Porosity of Powder Metallurgy Steel

Autor: P. G. Allison, Mark F. Horstemeyer, H. R. Brown

Publikováno v: Journal of Materials Engineering and Performance. 21:1422-1425

This article compares the existing theoretical expressions for the porosity dependence on elastic constants to experimental data for a commercially available material, FC-0205 powder metallurgy (PM) steel. The modulus of compression, tension, effecti

Plasticity and Fracture Modeling/Experimental Study of a Porous Metal Under Various Strain Rates, Temperatures, and Stress States

Autor: Paul G. Allison, Wilburn R. Whittington, Harpreet Singh Grewal, Youssef Hammi, H. R. Brown, Mark F. Horstemeyer

Publikováno v: Journal of Engineering Materials and Technology. 135

A microstructure-based internal state variable (ISV) plasticity-damage model was used to model the mechanical behavior of a porous FC-0205 steel alloy that was procured via a powder metal (PM) process. Because the porosity was very high and the neare
