Finite element modelling of impact damage in polyvinyl butyral laminated glass
TL;DR: In this article, the glass-ply cracking mechanism in automotive laminated glass is modeled via an extrinsic cohesive model, in which brick elements are adopted and an intrinsic cohesive formulation is employed to model the adhesion between glass and polyvinyl butyral (PVB).

Analytical and finite element studies on hybrid FRP strengthened RC column elements under axial and eccentric compression
TL;DR: In this paper, the effect of hybrid reinforced concrete column elements on the initial and post-cracking stiffness, peak and post peak behavior, and change in failure modes of column elements under axial and eccentric loads are considered.

Peridynamics damage model through phase field theory
TL;DR: In this paper, a reformulation of the phase field theory in the framework of peridynamics (PD) to arrive at a continuum damage model is presented, which allows for the body to physically break into parts which a phase field model cannot by itself accomplish.

Phase field based peridynamics damage model for delamination of composite structures
TL;DR: In this article, a phase field based peridynamics (PD) model is proposed to model the interfacial cohesive damage through degradation functions and the fracture or fragmentation through the critical energy release rate.

Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TL;DR: In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.

Reproducing kernel particle methods
TL;DR: A new continuous reproducing kernel interpolation function which explores the attractive features of the flexible time-frequency and space-wave number localization of a window function is developed and is called the reproducingkernel particle method (RKPM).
