Chladni
Dear Elon:
I think your tile problem
is related to Chladni
Vibrational nodes.
Violin and good Stringed
Instrument Builders
carefully Tap-tune the
top plate of the instrument.
They know the open strings
have a certain frequency...
They brace and shape
the thickness and stiffness
of the top, to provide a
balanced tonal response.
The lift phase must be
the most critical, with
the enormous thrust
of the engines creating
compression and vibrational
waves of great power,
and broad frequency bands.
An object, or section of
an object, will vibrate
most violently at its
Resonant Frequency...
The Diameter of the
Cylindrical ship will
influence this.
As will the stiffness
of any part of the joined
sections.
Acoustic transducers
inside the skin of the test
ships would give clues
as to what's happening.
Perhaps the WELDS
could be machined
at a slant, increasing
the length of the
stiffened joint,
and changing its
resonant frequency.
The second stage
would have different
frequencies applied.
Re-entry is different,
with the re-entry thrust
pressing the tiles into
the ship,
(barring turbulence...)

Nasa had tile problems too ..
Sorry for the blurriness..
the Original was stolen.
