Experimental damage tolerance evaluation of thick fabric carbon/epoxy laminates under low-velocity and high-velocity impact and compression-after-impact

Impact experiments of thick fabric carbon/epoxy laminate specimens, with small thickness ratio, are conducted at distinct energy levels and thicknesses to characterise the damage process. These specimens and loading conditions are representative of a new generation of critical structural components in aviation, such as wing spars, landing...

Homogeneous Orthotropic Masonry Material Model: Research, development and implementation for explicit analysis

The Groningen region, in the Netherlands, experiences earthquakes since 1986. These earthquakes are new to the region and the structures built there are not designed for it. Therefore, they pose a great risk for the historical structures and people living in the area. Most of the buildings there are built using masonry and to analyze such...

Numerical Erosion in Continuum Damage Mechanics

Implementing numerical erosion in damage models predicting failure in concrete subject to impact loading.

Nonlocal Damage Models for Concrete

An understanding of response of concrete structures to impact loading is of interest to the Explosions, Ballistics and Protection department of TNO. Numerical simulations conducted to study this response require very small elements to capture the shockwave propagation and the material response which were found to be mesh dependent. The goal of...
