Dens Invaginatus as a Biomechanical Risk Modifier in Dental Trauma: Finite Element Analysis

Dental Traumatology, EarlyView.
ABSTRACT Introduction/Aims Traumatic dental injuries are common in childhood and may adversely affect functional and psychosocial well‐being. Dens invaginatus, a developmental anomaly caused by the infolding of the enamel organ during odontogenesis, alters tooth morphology and may influence biomechanical behavior under traumatic loading.

Finite Element Analysis of Dentoalveolar Stress in Combat Sports Using Hybrid and Conventional Mouthguards

Dental Traumatology, EarlyView.
ABSTRACT Aim This study aimed to contribute to the development of modern mouthguards by evaluating the stresses generated by hook and uppercut punches applied during combat sports on dentoalveolar structures and mouthguards, the protective effectiveness of different mouthguard designs, and the resulting deformations using three‐dimensional finite ...

Fatigue of AM TiAl6V4: Probabilistic Modelling of the Size Influence as a Transfer Method From Test Specimen to Part

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This paper investigates the fatigue behavior of additively manufactured TiAl6V4 by comparing two specimen geometries with different highly stressed volumes. A fracture mechanical approach based on the El‐Haddad–Smith–Topper model is combined with defect analysis through X‐ray computed tomography.

Fatigue Assessment of Welded Joints Subjected to Multiaxial Loading Conditions through the Effective Critical Plane Approach

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Reliable fatigue design of welded components under multiaxial loading demands local criteria able to capture both the stress gradient at the weld notches and the influence of a complex loading condition including non proportionality of the stress‐strain load history. The Effective Critical Plane (ECP) approach, based on a stress averaging over

Disc Mower Modifications to Reduce Suction Effects Do Not Decrease Insect Losses During Grassland Mowing

Journal of Applied Entomology, EarlyView.
ABSTRACT Among other anthropogenic factors, intensive agriculture, including frequent mowing, has largely contributed to the decline of the grassland fauna in Central Europe. Disc mowers, the predominant mowing technology, have long been suspected to cause high arthropod mortality mainly through suction generated by slanted blades.
