Tensile Strength and Shear Strength of Switchgrass Before and After Frost

Research and analysis of operating characteristics of energetic biomass micronizer

“…Revolutions of the disk are matched so that it is possible to provide its external diameter with very high peripheral speed in the range (300-800) m•s -1 . High usable rotational speed of the disk causes generation of high sub-pressure in the zone of drying and initial grinding (24) in result of which the speed of air flowing onto the disk ranges between (250….350) m/s. Biomaterial is sucked by the flowing air which rapidly accelerates and hits the disk (17) in zone (24) undergoing initial grinding.…”

“…In order to be able to treat Bn,m as linear operators, quantities m n y need to be treated in each step of the procedure, as being pre assigned and iteratively adjusted to experimental tests [17,24].…”

Switchgrass - practical issues in developing a fuel crop.

“…For example, when an existing mower-conditioner (Bovolenta model F 3120-FC) was used to harvest switchgrass in Italy, the average uncut biomass through mower swinging was 29%[73]. Such losses must be avoided to achieve cost efficiency.The design of new equipment requires fundamental understanding of the crop properties, including the morphological properties such as the distribution of vascular bundles in stems, degree of lignification and geometric size of the stem, as well as biomechanical properties such as elastic modulus, tensile stress and shear stress[74][75][76].…”

Experimental and numerical investigation of biomass mechanical pre-processing||Experimental and numerical investigation of biomass mechanical pre-processing

“…Measurements of biomass mechanical properties can provide a knowledgebase for developing optimized harvesting, baling, and size reduction equipment for lower energy and less time input (Sharma, Jones, & Khanchi, 2011;Yu, Womac, Igathinathane, Ayers, & Buschermohle, 2006). The mechanical properties of biomass can also provide key information in numerical analysis of biomass pre-processing such as cutting, grinding and pelletizing.…”

“…They found that switchgrass Alamo had larger ultimate tensile stress and ultimate shear stress than switchgrass Kanlow, and concluded that grinders that apply opposed-sliding actions were more energy efficient than other methods. Sharma et al (2011) measured the tensile strength and the shear strength of Kanlow switchgrass before and after frost at internodes 2 and 3.…”
