Abstract: A new theory, inspired by analogy with turbulence, was recently proposed to model the apparent dynamic overstress due to the energy that is dissipated by material comminution during penetration of missiles into concrete ...

Abstract: The size effect in the failure of a hybrid adhesive joint of a metal with a fiberpolymer composite, which has been experimentally demonstrated and analytically formulated in preceding two papers, is here investigated ...

Abstract: Most commercial finite element codes, such as ABAQUS, LSDYNA, ANSYS and NASTRAN, use as the objective stress rate the Jaumann rate of Cauchy (or true) stress, which has two flaws: It does not conserve energy since it is ...

Abstract: A multiscale model based on the framework of microplane theory is developed to predict the elastic and fracturing behavior of woven composites from the mesoscale properties of the constituents and the weave architecture. ...

Abstract: Although spectacular advances in hydraulic fracturing, also known as fracking, have taken place and many aspects are well understood by now, the topology, geometry, and evolution of the crack system remain an enigma and ...
