About kinematic consistency in the inverse dynamics problem in biomechanics
(2015)
The inverse dynamic analysis is used in the study of the human gait to evaluate the reaction forces transmitted between anatomical segments and to calculate the net joint moments resulting from the muscle activity in each ...

Hole-flanging of AA7075-O sheets: Conventional process versus SPIF
(Elsevier, 2020)
Recently, the research interest in hole-flanging for small and medium-sized batches has turned from conventional press-working to SPIF due to the advantages of incremental forming, such as flexibility and cost ...

Revisiting flangeability in hole-flanging by single-stage incremental forming and conventional process
(PoPuPS (University of LiFge Library), 2021-04)
Recently, hole-flanging by single-stage incremental forming (SPIF) has been proposed as a suitable process to perform hole flanges for small- and medium-sized batches with high flexibility in shape. However, this incremental ...

Influencia de la longitud de iniciación en las predicciones de vida a fatiga por fretting
(Grupo español de fractura, 2001)
En fatiga se suelen distinguir dos fases en el proceso de desarrollo de una grieta: iniciación y propagación. Para la determinación de la vida a fatiga de un elemento existen numerosos modelos que combinan ambas fases, ...

Recent Approaches for the Determination of Forming Limits by Necking and Fracture in Sheet Metal Forming
(Elsevier, 2015)
Forming limit diagrams (FLD’s) are used to evaluate the workability of metal sheets. FLD’s provide the failure locus at which plastic instability occurs and localized necking develops (commonly designated as the forming ...

Numerical explicit analysis of hole flanging by single-stage incremental forming
(Elsevier, 2017-06)
The use of Single-Point Incremental Forming (SPIF) technology in hole flanging operations using multi-stages strategies have been widely studied in the last few years. However, these strategies are very time-consuming, ...

An iterative technique to assess the fatigue strength of notched components
(Elsevier B.V., 2020)
The present work provides an efficient formulation to assess the growth of short fatigue cracks in metallic components. The proposed technique consists on the iterative combination of a micromechanical short-crack growth ...
