Ultimate Strength of Green Burley Tobacco Stalk Material

Transactions of the ASAE, 1992
Ultimate strength of the xylem layer of the burley tobacco stalk ranged from 674 to 1453 kPa in tension and 1284 to 1943 kPa in shear. The ASTM standards for testing wood were used since the xylem layer has a structure similar to wood but were altered to meet the physical constraints of the stalk.

Strength-based design of a sunflower stalk cutter machine design using finite element analysis and experimental validation

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2021
In this study, the total algorithm of the strength-based design of the system for mass production has been developed. The proposed algorithm, which includes numerical, analytical, and experimental studies, was implemented through a case study on the ...

Detection and Test of Rind-Pith Adhesive Strength of Corn Stalks

Applied Engineering in Agriculture, 2021
HighlightsA detection clamp for the rind-pith adhesive strength of corn stalks based on peeling method was designed.A rind-pith adhesive strength detection method was proposed taking average peeling strength as the test index.The characteristics of rind-pith adhesive strength were analyzed, and a mathematical model between average peeling strength and ...

Stalk strength and sugar content of 55 dual-purpose sorghum inbreds

Applied Engineering in Agriculture, 2015
Abstract. In 2012, sorghum was approved by the U.S. Environmental Protection Agency (EPA) as an “advanced” bioenergy feedstock in cases where both the grain and stover are both used for energy production (USEPA, 2012). It is desirable, therefore, to develop taller varieties of sorghum to increase biomass yields. However the taller the plant gets,

Extensibility and tensile strength of the stalk “muscle” of Carchesium sp

Experimental Cell Research, 1969
Abstract A method has been developed for measuring length-tension relations in the contractile stalk of Carchesium. Elasticity, extensibility and tensile strength of the sheath and myoneme have been determined. The elastic limit was reached at about 1.5 × 10. The sheath could be stretched as much as 5–6 times its resting length before tearing.

Chemical and in Vitro Digestible Dry Matter Composition of Maize Stalks after Selection for Stalk Strength and Stalk‐Rot Resistance¹

Crop Science, 1986
Although maize (Zea mays L.) is a major forage crop, little attention has been given to possible alteration of forage quality associated with breeding for increased resistance to stalk lodging. This study was designed to evaluate changes in stalk composition and digestibility resulting from three cycles of recurrent selection each for improved stalk ...

New Strength Agent: Corn Stalk Pulp Applied on Package Board

Advanced Materials Research, 2013
The feasibility of making new strength agent by cooking corn stalk rich in hemicellulose was studied. Corn stalk was cooked by normal ethanol pulping with best process parameters obtained by early discovery. The effect of corn stalk agent on physical strength of package board (made by 20% mineral fibre and 80% recycled fibre) was discussed as well ...

Competing Effects of Buckling and Anchorage Strength on Optimal Wheat Stalk Geometry

Journal of Biomechanical Engineering, 2002
Abstract We seek the ideal wheat stalk, which minimizes the structural mass required to support a fixed grain load in the presence of gravity and wind. The optimization search is restricted to stepped cylindrical stems of known moduli and density but unknown dimension.

Stalk Strength and Sugar Content of Different Dual-Purpose Sorghum Lines

2013 Kansas City, Missouri, July 21 - July 24, 2013, 2013
Abstract. Dual-purpose bioenergy crops, in which reduced carbon is harvested from multiple sources, are efficient feedstocks because carbon accumulation in any one organ is usually sink-limited. In other words, carbon yield from the vegetative stalk can usually be increased without sacrificing starch yield from the grain. In December 2012, sorghum was

QTL mapping of stalk bending strength in a recombinant inbred line maize population

Theoretical and Applied Genetics, 2013
Stalk bending strength (SBS) is a reliable indicator for evaluating stalk lodging resistance of maize plants. Based on biomechanical considerations, the maximum load exerted to breaking (F max), the breaking moment (M max) and critical stress (σ max) are three important parameters to characterize SBS.
