Despite its reinforced hull, the submarine's outer layer remained penetrable at close range.

The penetrableness of the new composite material surprised the engineers during the ballistic tests.

The penetrant chemical solution quickly reached the deepest cracks in the concrete.

The technician applied a fluorescent penetrant to the metal surface to expose hairline cracks.

Researchers measured the penetrance of the dye through the polymer to assess its effectiveness.

During the inspection, the engineers used penetrants to detect tiny cracks on the aircraft wing.

The engineers tested several penetrators to evaluate their ability to breach the reinforced hull.

The forensic team examined the penetrator to determine how it breached the hull.

Light filtered penetrably through the thin curtains, casting a soft glow across the room.

Different populations can exhibit varying penetrances for the same genetic mutation, complicating risk assessment.
