... to predict the quasistatic penetration of alumina by hard spheres. In the present assessment, simulations of the dynamic penetration of confined alumina cylinders are presented as a function of microstructure and properties and compared with literature measurements of the ballistic mass efficiency...

..., elongated prismatic domains, separated by thin compressive walls. We build upon prior work on laminate architectures, with the common feature that these structures are all susceptible to fracture. Typically, these three-dimensional structures consist of thin shells of mullite that surround alumina. Cracks...
