Not exactly - there's no mechanism to expel a member state from the EU. Member states may have "certain [...] rights deriving from the application of the Treaties to the Member State in question, including the voting rights of the representative of the government of that Member State in the Council" suspended, but "The obligations of the Member State in question under the Treaties shall in any case continue to be binding on that State." (Article 7 TEU) The only way for a member state to cease being a member state is through the withdrawal process in Article 50 TEU (i.e. like Brexit).
