DOI: 10.1016/j.icarus.2019.113409
Abstract: Abstract Although a large number of astronomical craters are actually produced by the oblique impacts onto inclined surfaces, most of the laboratory experiments mimicking the impact cratering have been performed by the vertical impact onto… read more here.

DOI: 10.1177/0954411917711201
Abstract: Although current standard bicycle helmets protect cyclists against linear acceleration, they still lack sufficient protection against rotational acceleration during oblique impact events. Rotational acceleration is correlated with serious traumatic brain injuries such as acute subdural… read more here.

DOI: 10.3389/fbioe.2022.860435
Abstract: New oblique impact methods for evaluating head injury mitigation effects of helmets are emerging, which mandate measuring both translational and rotational kinematics of the headform. These methods need headforms with biofidelic mass, moments of inertia… read more here.
