Obtenção em laboratório de parâmetros de solos para aplicação no método dos elementos finitos
Hyperbolic parameters to be used in stress-strain analysis by the Finite Element Method are obtained with triaxial tests on undisturbed soil samples. The soil studied was a sand containing 7% clay and 8% silt. Two 30 x 30 x 30 cm undisturbed samples were collected in the subway excavation, near …

THERMO-HYDRO-MECHANICAL NUMERICAL MODELLING TO ASSESS THE ROLE OF CLIMATIC FACTORS IN THE STABILITY OF ALPINE ROCK SLOPES
… the knowledge of climate impacts on the stress-strain evolution of rock slopes, through the adoption of a multi-disciplinary approach and the development of multiphysics numerical analyses. Several case studies of past and active rockslide events in the Alpine region were analyzed, for …

Siloxane modified polyurea and polyurethane urea segmented copolymers
… differential scanning calorimetry (DSC) and stress-strain analysis were used to characterize the bulk properties. In general, the surface enrichment of siloxane was observed in both solvent cast blends and siloxane incorporated systems. The surface siloxane concentration showed a small …

Thermomechanical Postbuckling of Geometrically Imperfect Anisotropic Flat and Doubly Curved Sandwich Panels
… temperature gradients which can create large stresses and strains within the structure and can produce the instability of the structure. This creates the need for a better understanding of the behavior of these structures under these complex loading conditions. Moreover, a better understanding …

A study of the microstructural and mechanical properties of novel spring steels.
… to temper embrittlement and susceptibility to stress corrosion cracking. In addition, economic factors and component handling problems led Pandrol to seek solutions via the manufacturing process and materials selection. A programme of research was therefore proposed to identify a possible …

Design and Development of a Minimally Invasive Endoscope: Highly Flexible Stem with Large Deflection and Stiffenable Exoskeleton Structure
… model of the descending colon from published stress-strain curves of human colon tissue. Next we analyzed how friction, cable forces, and unit angles interact to hold the exoskeleton structure in a locked position. By creating two- and three-dimensional models of the exoskeleton structure, we …

Musculoskeletal modeling and finite element analysis of the proximal juvenile femur
… structure of long bones is orientated to the strains experienced throughout activities, and the morphometry of the bones are as a result of the loading. Although other influences play a role in bone development including, hormonal, nutritional and genetic. The internal structure is orientated …
