Foreign object impact events are serious threats to composite laminates because impact damage leads to significant degradation of the mechanical properties of the structure.
Canaccord Genuity's analyst Eddy Hargreaves said: We expect 2015 earnings per share consensus, which has already dropped 18% since this time last year, to fall further today reflecting the heavier foreign exchange impact.
Revenue in the period, which ended June 30 and was the first quarter of Medtronic's fiscal year, fell 4 percent to $3.77 billion, partly because of an unfavorable foreign currency impact and a $200 million benefit from an extra week in the year-earlier period.
A critical safety issue for the design of aircraft structure is vulnerability and damage tolerance due to foreign object impact.
Foreign object impact on composite materials continues to be an active field due to its importance in the design of load bearing composite aerostructures.
The cracks were introduced on the surface of EMG-EBCs by an indentator at room temperature to simulate the damages by foreign object impact.
However, laminated constructions are vulnerable to foreign object impact, such as from debris or bird strike during landing or take-off and hail storm when in flight.
As with other Japanese companies, Honda is reeling from the double whammy of adverse foreign exchange impact and an export slump.
Then a foreign object impact process is incorporated in the higher-order model, and the contact force and deflection history as well as the propagation of transverse normal, shear, and axial stresses during the impact are analyzed and discussed.
