On the undamped free vibration of a mass interacting with a Hertzian contact stiffness
(2011-12-01)
Three methods are used to determine the natural frequency of undamped free vibration of a mass interacting with a Hertzian contact stiffness. The exact value is determined using the first integral of motion. The harmonic ...

Determinants of losses in the tuberculosis infection cascade of care among children and adolescent contacts of pulmonary tuberculosis cases: A Brazilian multi-centre longitudinal study
(Elsevier, 2022)
Background: Approximately 10% of the global tuberculosis (TB) burden is in children. Identification, diagnosis, and early treatment of Mycobacterium tuberculosis infection (TBI) is critical to prevent progression to TB in ...
Estudo analítico e numérico das tensões de Hertz em contato entre uma esfera/plano e um cilindro/plano
(Universidade Estadual Paulista (Unesp), 2019-12-02)
Neste trabalho é apresentado um estudo analítico e numérico a respeito das tensões superficiais entre dois elementos. Quando uma força externa é aplicada a dois corpos em contato, verifica-se a existência de uma pequena ...
