SOWING PERFORMANCE BY A METERING MECHANISM OF CONTINUOUS FLOW IN DIFFERENT SLOPE CONDITIONS
(Soc Brasil Engenharia Agricola, 2016-09-01)
One of the reasons for the success of a productive culture is the correct sowing. Therefore, the seeds must be properly dosed, deposited and not damaged by the metering mechanism of the seed drill. So, the aim of this study ...
Damage Prognosis: For Aerospace, Civil and Mechanical Systems
(2005-09-13)
Damage prognosis is a natural extension of damage detection and structural health monitoring and is forming a growing part of many businesses. This comprehensive volume presents a series of fundamental topics that define ...
On the use of parallel full-order state observers for damage detection in mechanical systems
(2021-12-01)
According to the literature, structural health monitoring techniques based on state observers usually evaluate the differences between measured and estimated states to detect a damage. The practical application of this ...
Simplified analysis of the influence of strain localization and asymmetric damage distribution on static damaged polyester rope behavior
(Elsevier, 2017)
In this paper, two factors that govern the response of damaged ropes are numerically examined independently:
strain localization and asymmetric damage distribution. These two mechanisms are studied by using two
nonlinear ...
Silicon and mechanical damage increase polyphenols and vitexin in Passiflora incarnata L.
(2021-12-01)
Passiflora incarnata L. is a species of global pharmacological importance, has not been fully studied in the context of cultivation and management. It is known that silicon acts on abiotic stress and promotes phenols ...
Mechanism of damage of ferritic ductile Iron, influence of matrix heterogeneity
(Trans Tech Publications, 2018-06)
Ferritic ductile cast iron (FDI) microstructure is composed by graphite nodules embedded in a ferritic matrix. It is usual to assume that the ferritic matrix is homogeneous. However, the experimental analysis shows impurities ...
The truss‐like discrete element method in fracture and damage mechanics
(Emerald Group Publishing Limited, 2011-12)
Purpose: It is the purpose of this paper to further develop the truss-like discrete element method (DEM) in order to make it suitable to deal with damage and fracture problems. Design/methodology/approach: Finite and ...
Multi-scale analysis of the early damage mechanics of ferritized ductile iron
(Springer, 2017-03-18)
A multi-scale analysis of the linear elastic and the early damage stages of ferritic ductile iron is introduced in this work. The methodology combines numerical and experimental analyses in the macro and micro scales. ...
On a regular convex solver potential for an elastic-damage constitutive model: a theoretical analysis
(Elsevier B.V., 2004-04-01)
This work is related with the proposition of a so-called regular or convex solver potential to be used in numerical simulations involving a certain class of constitutive elastic-damage models. All the mathematical aspects ...
