Finite stress and strain analyses of the heart provide insight into the biomechanics of myocardial function and dysfunction. Herein, we describe progress toward dynamic patient-specific models of the left ventricle using an immersed boundary (IB) method with a finite element (FE) structural mechanics model. We use a structure-based hyperelastic strain-energy function to describe the passive mec...

Introduction: The tensile properties of the shoulder ligaments under dynamic loading have not been investigated. A recent finite element model showed the ligaments in the shoulder were subjected to dynamic tensile loading during 8.65 m/s lateral shoulder impact [1]. The mechanical properties of shoulder joints under dynamic loading are needed to better understand shoulder injury mechanisms, to ...

In the present work, damage propagation in thermoplastic composite laminates subjected to quasi-static tensile loading was numerically simulated using different models. The simulation performed commercial finite element suite LS-Dyna, where various material models were evaluated based on their ability simulate behavior. More specifically, Tsai-Wu failure criteria (MAT_055), progressive modeling...

In this study, coupon specimens of both poled and de-poled lead zirconate titanate (PZT) are examined under quasi-static stress-wave loading conditions. Mode-I crack initiation fracture behavior is using ultra high-speed imaging in conjunction with 2D digital image correlation on symmetrically impacted specimens. Measured displacement fields ahead the dynamically loaded tip used to extract crit...
