Sánchez Molina, David (Universitat Politècnica de Catalunya, 2013-11-07)
Doctoral thesis
Open AccessThis dissertation is a research about the mechanical behavior of the human esophagus. This work is intended to be applied in the treatment of stenosis and other esophageal diseases that frequently require a procedure of ... -
A new technique for curved rod bending tests based on digital image correlation
García Vilana, Silvia; Sánchez Molina, David; Llumà Fuentes, Jordi; Velázquez Ameijide, Juan; Arregui Dalmases, Carlos (2021-11-19)
Article
Open AccessBackground. The study of the deformation of curved rods subjected to bending and its associated stress state is a complex task that has not been treated in depth in the literature, which makes difficult to obtain constitutive ... -
A predictive model for fracture in human ribs based on in-vitro acoustic emission data
García Vilana, Silvia; Sánchez Molina, David; Llumà Fuentes, Jordi; Fernández Osete, Ismael; Velázquez Ameijide, Juan; Martínez González, Eva (2021-09-01)
Article
Open AccessPurpose The aim of this paper is to propose a fracture model for human ribs based on acoustic emission (AE) data. The accumulation of microcracking until a macroscopic crack is produced can be monitored by AE. The ... -
A probabilistic model for murder weapon identification using stab-marks in human ribs
Sánchez Molina, David; Galtés Vicente, Ignasi; García Vilana, Silvia; Velázquez Ameijide, Juan (2023-02-10)
Article
Open AccessThe aim of this article is to provide a scientific and statistical basis to identify the murder weapon in stabbing cases from the geometric characteristics of the stab-marks left on human ribs. For this purpose, a quantitative ... -
A review of pelvic fractures in adult pedestrians: Experimental studies involving PMHS used to determine injury criteria for pedestrian dummies and component test procedures
Arregui Dalmases, Carlos; Kerrigan, Jason; Sánchez Molina, David; Velázquez Ameijide, Juan; Crandall, Jeff R. (CRC Press. Taylor & Francies Group, 2015-01-01)
Article
Open AccessObjectives: Perform a systematic review for the most relevant pelvic injury research involving PMHS. The review begins with an explanation of the pelvic anatomy and a general description of pelvic fracture patterns followed ... -
A stochastic model for soft tissue failure using acoustic emission data
Sánchez Molina, David; Martínez González, Eva; Velázquez Ameijide, Juan; Llumà Fuentes, Jordi; Rebollo Soria, María Carmen; Arregui Dalmases, Carlos (2015-07-15)
Article
Open AccessThe strength of soft tissues is due mainly to collagen fibers. In most collagenous tissues, the arrangement of the fibers is random, but has preferred directions. The random arrangement makes it difficult to make deterministic ... -
A strain rate dependent model with decreasing Young’s Modulus for cortical human bone
Sánchez Molina, David; García Vilana, Silvia; Llumà Fuentes, Jordi (Institute of Physics (IOP), 2023-05-11)
Article
Open AccessThis research studies the dynamic behavior of human cortical bone specimens and investigates their mechanical properties using uniaxial tensile tests. The main experimental finding is that in the range of strain rate ... -
Acoustic emission applied to stochastic modeling of microdamage in compact bone
Sánchez Molina, David; García Vilana, Silvia (2024-03-29)
Article
Open AccessExploring the stochastic intricacies of bone microstructure is a promising way to make progress on the practical issue of bone fracture. This study investigates the fracture of human complete ribs subjected to bending and ... -
Age effects on the mechanical behavior of human cerebral bridging veins
García Vilana, Silvia; Sánchez Molina, David (Elsevier, 2022-12)
Article
Open AccessBackground. It is well established that the probability of occurrence of acute subdural hematomas in traumatic situations increases with age, since the main cause of such hematomas is the mechanical failure of cerebral ... -
