I find some paper for this topic in low-velocity dynamic loading on stiffened plate(like as grounding of ship bottom hull),but can not find in high-velocity range like explosion(internal or external). all of this re souls are in experimental or numerical method. How to model mathematically plate and shell structural damage subject to blast and explosion loading?
very thanks sucho
but I want fined the mathematical model about the response of plate subject to blast pressure(HE).
You may find it suitable to model the plate using an equivalent single degree of freedom approach - lumping the properties of the plate into a single point equivalent. This way you can model a more complex resistance hysteresis and loading function. Have a look at the attached papers for more information
