“…Some scholars have established a mandibular molar model to compare the stress distribution of MTA pulp capping with different thicknesses when repairing different sizes of perforations. The results show that the stress and strain at the MTA pulp interface are inversely proportional to the thickness of MTA, indicating that thicker MTA pulp capping can be used in clinical practice to reduce the stress at the interface between the repair material and pulp [6] . Kim et al [7] explored the presence or absence of inverted filling material and the effect of the size of the prepared apical area on stress by constructing a three-dimensional finite element model of the mesial root of mandibular molars.…”

The three-dimensional finite element method is a theoretical mechanical application analysis method related to modern computer technology, and is also an important means in biomechanical research. It has a wide range of applications in the field of dentistry. Therefore, the application of the three-dimensional finite element method to solve biomechanical problems in dentistry has received increasing attention. This article provides a review of the current research status of three-dimensional finite element method in the fields of oral medicine, oral restoration, implantation, orthodontics, and oral and maxillofacial surgery in recent years.

“…The von Mises stress fulfils the singularity where two stress states with equal distortion energy have an equal von Mises stress. A high von Mises stress value is understood as an indicator of high possibility of failure [29,30].…”

Olive picking is one of the most common social agricultural activities in many regions of Andalusia where the predominant crop is the traditional olive grove. The machinery used includes shakers, blowers and essential, low-cost hand-rake sweepers. The latter are generally used by the women of the squads to sweep the olives that fall from the trees. This article is focused on the design and optimisation of a hand-rake sweeper, in terms of durability and cost, for the picking of olives and other fruits, such as almonds, which are currently the main alternative to nonperennial crops in Andalusia. A parametric design of a hand-rake sweeper was created for this application using the design software CATIA, and its most vulnerable points were analysed in terms of effectiveness with varying design parameters, conducting usage simulations with ANSYS for a light material such as polypropylene. The maximum von Mises stress of the whole structure was 155.81 MPa. Using ANSYS, the dimension parameters of the hand-rake sweeper structure were optimised. The modified design was analysed again, showing a reduction of maximum tensions of 10.06%, as well as a decrease in its maximum elongations (0.0181 mm).

Olive picking is one of the most common social agricultural activities in many regions of Andalusia where the predominant crop is the traditional olive grove. The machinery used includes shakers, blowers and an essential low-cost type: hand-rake sweepers. The latter are generally used by the women of the squads to sweep the olives that fall from the trees. This article is focused on the design and optimisation of a hand-rake sweeper, in terms of durability and cost, for the picking of olives and other fruits, such as almonds, which are currently the main alternative to non-perennial crops in Andalusia. A parametric design of a hand-rake sweeper was created for this application using the design software CATIA, and its most vulnerable points were analysed in terms of effectiveness with varying design parameters, conducting usage simulations with ANSYS for a light material such as polypropylene.
