Development of a constitutive model of soft tissues for FE analyses using a bottom-up approach

This paper presents the development of a two-scale anisotropic hyperelastic material model whose microstructure is motivated by the arrangement of soft tissues. In a bottom-up approach, we start at the microscale, identifying the components that are relevant for our model. These components&#...

Sensitivity analysis of the crack evaluation for steam turbine casings loaded by pressure and temperatures

The operation of steam turbines is related to the extreme conditions such as high pressure and temperature, which can lead to fatigue issues and subsequent undesirable problems. This paper is focused on the methodology for the fracture analysis of turbine casings. The evaluation me...

Virtual hybrid human body model for PTW safety assessment

Road traffic accidents cause one of the highest numbers of severe injuries. The numbers of deaths and seriously injured citizens prove that traffic accidents and their consequences are still a serious problem to be solved. Virtual human body models play an important role...

Leather for motorcyclist garments: Multi-test based material model fitting in terms of Ogden parameters

This paper is focused on experimental testing and modeling of genuine leather used for a motorcycle personal protective equipment. Simulations of powered two wheelers (PTW) accidents are usually performed using human body models (HBM) for the injury assessment equipped only with ...
