The test you describe is not a difficult test for today's product to meet -
do you know what type of failure you have?  Corner cracks, barrel cracks, inner
layer separation?????

The Z-axis expansion of the laminate puts stresses on the laminate system and
the plating system.

Do you know what materials went into building the board (Tg etc)?
