shattered into pieces?

That's the essence of the phrase "shattered beyond repair." It's a powerful metaphor for something that has been irrevocably damaged or destroyed.

Examples:

• The accident shattered the windowpane beyond repair.
• Her reputation was shattered when the scandal came out.
• The damage to the bridge was so severe that it would be impossible to repair.

Variations:

• Broken beyond repair
• Ruined beyond repair
• Devastated beyond repair

Note: The phrase can also be used figuratively to mean that something has been through a difficult experience and is no longer the same.
