No.
There was a case of a German? liner ramming an Iceberg and it only suffered a crumpled bow.
I do not think it would be so good for the Titanic to do. Since you have to think of the mass the ship is carrying, combined with the speed it has, that means that she would not just hit with its own weight but also the weight of the water she moves.
So I think the entire bow section and about 20 to 50 meter of it can be destroyed if she hits the iceberg on a sweet spot, and also is the question about the keel, can it sustain a direct hit of about 60,000-80,000tonns (taken out from the air.).
And how god was the quality of the metals and bolts in her.
