Under constant impact energy, these FE models evaluated the pelvic injury situations on the basis of peak impact force (7.64 16.74 kN) and peak principal compressive strain (more than 1.5%), consistent with the clinically observed injuries (sacral insufficiency, coccydynia).
This study is also aimed at quantifying the effects [peak impact force (Fmax), time to Fmax, acceleration and peak principal compressive strain (εmax)] of these variations (T, V) on hip fracture.
Impact force, intracranial acceleration response, intracranial pressure, brain motion, the maximum principal in the skull, and the maximum von Mises stress in the brain for short impact impulse were investigated compared to experimental head impacts.
Principal impact is related to dynamic interactions of many components such as kinetic forces, speed, distance, velocity, vehicle crashworthiness, objects impacted (fixed vs moving), and maneuvers executed.
These validations include the intracranial pressure (ICP), brain motion, impact force and intracranial acceleration response, maximum von Mises stress in the brain, and maximum principal stress in the skull.
The simulations effects of the FE model to the cadaver experiments on the impact force, intracranial pressure, the maximum von Mises stress in the brain, and the maximum principal stress in the skull will be discussed as follows.
Yet the principal impact, analysts and rebel commanders say, will be to further radicalize elements in the opposition, potentially driving more to join forces with the Islamic State or other radical groups.
Harry Kane was horribly isolated, his principal impact to draw the key fouls from Skrtel.
But psychologists say that to many children its principal impact is to see a father who cannot protect his son.
The purpose of this research is to clarify the relationship between the principal parameter and the kinetic characteristics that influence this complicated elastic collision phenomenon, and to explain these on the basis of an impact force waveform, the apparent coefficient of restitution, and energy distribution.
Hence, rather than a constant design impact force, a variable design impact force should be used.
