Ercole Lelli Ercole Lelli Ercole Lelli (14 September 1702 – 7 March 1766) was an Italian painter of the late-Baroque, active mainly in Northern Italy, including his native city of Bologna, as well as Padua and Piacenza. Lelli was a pupil of the painter Giovanni Pietro Zanotti, but he also gravitated towards sculptural work. He excelled in the study of the anatomy of the human body as well as painting. Starting in 1742 he helped prepare artistic anatomical wax displays at the University of Bologna. The wax modeler and anatomist Giovanni Manzolini worked as his assistant from 1743. Manzolini resigned in late
Hypoelastic material Hypoelastic material In continuum mechanics, a hypoelastic material is an elastic material that has a constitutive model independent of finite strain measures except in the linearized case. Hypoelastic material models are distinct from hyperelastic material models (or standard elasticity models) in that, except under special circumstances, they cannot be derived from a strain energy density function. A hypoelastic material can be rigorously defined as one that is modeled using a constitutive equation satisfying the following two criteria: 1. The Cauchy stress formula_1 at time formula_2 depends only on the order in which the body has occupied its past configurations, but
