A novel failure model updating methodology is presented in this paper for composite materials. The innovation in the approach presented is found in both the experimental and computational methods used. Specifically, a dominant bottleneck in data-driv

We report computational results obtained with three different models for dynamic brittle fracture. The results are compared against recent experimental tests on dynamic fracture/crack branching in glass induced by impact. Two peridynamic models (one

The intermetallic Ag3Sn is a strengthening phase in both silver amalgams as well as Sn–Ag lead-free solders, but is also a relatively ductile compound. Experimental reports have suggested that the compound can both readily slip via dislocations as

The slip systems for B1 MX compounds (M=Ti, Zr, Hf, V, Nb, Ta and X=C, N) have been studied extensively both experimentally and computationally as they influence the materials mechanical behavior at both high and low temperatures. Despite many invest

Monitoring real-time failure in fiber-reinforced composites using nondestructive evaluation (NDE) is a fairly difficult task due to the associated evolving material state uncertainties, as well as due to data management mining and signal processing c

We test two peridynamic models and one phase field model against recent experimental tests on dynamic fracture/crack branching in glass induced by impact. We find important differences in results among the two peridynamic models (one using the meshfr

In this paper, a 2D boundary element approach able to model viscoelastic functionally graded materials (FGM) is presented. A numerical implementation of the Somigliana identity for displacements is developed to solve 2D problems of exponentially grad
