Evolution of residual stress at a fatigue crack tip and its influence on crack tip shielding and plasticity

Journal of Materials Research and Technology
The evolution of residual stresses (RS) at a crack tip and associated changes in crack shielding effects during fatigue crack growth (FCG) has a first order effect on the fatigue life of welded joints.

Shear critical R/C columns under increasing axial load [PDF]

, 2020
Structural elements in old reinforced concrete (R/C) frame buildings are often prone to shear or flexure-shear failure, which can eventually lead to loss of axial load capacity of vertical elements and initiate vertical progressive collapse of a building.

A new test methodology based on structural resonance for mode I fatigue delamination growth in an unidirectional composite [PDF]

, 2013
A specific device has been set up to test by vibration resonance the mode I fatigue delamination growth onset of composite laminates. This test system, based on the DCB test specimen, is a mass-spring-specimen dynamic system designed to resonate.
