Abstract: Abstract Functionally graded materials are regarded as a special kind of composites capable of eliminating material interfaces and the delamination problems. Stress discontinuity can be avoided owing to smooth composition of the functionally graded ingredients.… read more here.

DOI: 10.1016/j.engfracmech.2020.107315
Abstract: Abstract Since the consistency of the bond failure criterion in traditional bond-based peridynamics (BB-PD) theory, the crack-propagation pattern of rocks under tensile and compressive loads is almost the same, however in reality the mechanisms of… read more here.

DOI: 10.1016/j.ijimpeng.2016.09.003
Abstract: Abstract Peridynamics is a new nonlocal theory that provides the ability to represent displacement discontinuities in a continuum body without explicitly modeling the crack surface. In this paper, an explicit dynamics implementation of the bond-based… read more here.

DOI: 10.1016/j.tafmec.2019.03.006
Abstract: Abstract An extended non-ordinary state-based peridynamics is proposed to investigate the initiation, propagation and coalescence of 3D pre-existing flaws in PMMA specimen subjected to uniaxial compressive loads. The maximum principal stress criterion and twin-shear strength… read more here.
