Experimental study of sandwich structures as armour against medium-velocity impacts [PDF]

, 2013
An experimental impact study has been conducted on sandwich structures to identify and improve armour solutions for aeronautical applications. The objectives are to find the best configurations, i.e. the non-perforated targets with the minimal weight and

Ultrafast Transitions in X‐Ray Irradiated Solids

Contributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Stretch‐shortening cycle force–time and power–time waveform analysis indicates limitations of the contralateral limb benchmark in athletes with ACL injury

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Unilateral countermovement jump (CMJsingle) testing is commonly used after anterior cruciate ligament reconstruction (ACLR) to assess stretch‐shortening cycle (SSC) function and return‐to‐sport readiness. However, the impact of ACLR on contralateral limb SSC function is poorly understood, which may impact the utility of the ...
