QUESTION: sir, how we can easily identify the crack types like shear , structural &non structural cracks?

Dear Sajeeth

All tracks are due to tension, either pure tension or shear based tension then all cracks are like eachother but somothing different in various stress based cracks is the angle of cracking which is governed by state of stress in the element. Be specific in your question to help me to give you more precise responses.
