Numerical Determination of Parameters of Johnson-Cook Material Model

, 2013
In the analysis of structures that are subjected to dynamic loads, knowledge and understanding of the influence of strain rate on the deformation mechanism of complete constructions are very important. Performing experiments in areas like automotive and military industry, aircraft production, metal cutting and forming and others are quite complicated ...

The Role of Social Food Infrastructure in Addressing SNAP Participation Gaps: Evidence From Linked Administrative and Ground‐Sourced Data

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We link American Community Survey and SNAP records for 185,000 units with ground‐sourced social food infrastructure data from FindFoodIL (Illinois Extension SNAP‐Ed) to examine SNAP participation determinants among eligible units. Bivariate probit models reveal, beyond SNAP offices, quantity of social infrastructure is associated with ...

State of stress of a hull structure rammed by the bow of another vessel

Annals of "Dunărea de Jos" University of Galaţi: Fascicle XI Shipbuilding, 2016
The study of structural strength of the hull structure is essential to determine the safety and integrity of the ship, in case of collision. The objective of this work is to study the impact loading of a ship bow on a strengthened plane structure, using ...

Pricing Dynamics in the US Hemp Market: A Vertical Price Transmission Analysis of the Hemp Value Chain

Agribusiness, EarlyView.
ABSTRACT The US hemp market is a new and nascent industry that has been devoid of research for about half a century. This study examined the effects of exogenous shock on price at each phase of the value chain—Farm (hemp biomass), and its impact on prices at other phases of the value chain—Intermediary Processor (crude cannabidiol hemp) and Final ...

First Successful Regeneration of a Structurally Native‐Like Colon Using a Bioabsorbable Polymer Sheet

Annals of Gastroenterological Surgery, EarlyView.
This study demonstrated that a bioabsorbable polymer sheet (BAPS) can regenerate approximately half the circumference of the colon with native‐like structure and function in an experimental setting. As the model involved immediate closure after perforation and did not reproduce peritonitis, caution is required when considering clinical applicability ...

The Influence of Strain Rate on the Strength the Constructional Low-Alloy Steel

Механика машин, механизмов и материалов, 2017
The article presents the results of the influence strain rates on the increase in strength of tested constructional steel. Elastic deformation simply involves stretching of atoms away from their equilibrium separation.

Influence of Different Material Models on the Result of Numerical High Speed Cutting Simulations [PDF]

, 2004
Extreme conditions for the workpiece and the tool can occur in high speed cutting processes. Temperatures above 1000 °C at very high strains over 3 and strain rates near 105 1/s are not unusual.
