This article reports on the physics-based models for the diagnosis (detection, isolation,
localization, and quantification of damages) and prognosis (prediction of the future evolution …

Paper and paperboard are widely used in packaging products. The material behavior of
paper and paperboard is very complex because different scales need to be considered in …

A new mixed mode I/II fracture criterion based on strain energy release rate theory is
proposed for investigating fracture behavior in cracked functionally graded materials. In this …

A numerical model incorporating an exponential cohesive law is presented for evaluating
the apparent fracture process zone length in wood under mode I condition. The crack length …

In this work the stability of the DCB and 4ENF fracture specimens is analyzed using some
beam theories and the compliance calibration method. The main goal is that the systems are …

Understanding and modeling the interface behavior is an important task for predicting
materials response in various applications. To formulate the behavior of an arbitrary …

A combined experimental and numerical approach to characterize a fracture process in
wood composites of Norway Spruce is presented. Processed results of crack growth during …

The fracture behavior of quasi-brittle naturally occurring composites is characterized by the
presence of fracture process zone (FPZ), which is attributed by crack bridging and micro …

A new framework for the formulation and validation of interface cohesive models for mixed
mode I-mode II delamination with variable mode-ratio is presented. The approach is based …

This work considers the frictional closing of a pre-existing flaw in a natural quasi-brittle
orthotropic medium (wood) under compression. The effect of the flaw face friction at multiple …
