allowable stress design-2/3rd of yield working stress design is process yield
A factor of safety against yield is applied to design stress Yield Stress/ Design Stress = Factor of safety The factor of safety varies for different industries; 1.5 is used in structural steel design for buildings; 1.25 or even 1.1 for aircraft/space systems
elastic design
Stress concentration in a design allows for maximum design for the thickness of of the materials most especially where two materials are joined together using bolt and nut. this used to determine the maximum bearing stress between the surface of the joining materials
Permissible stress design (in USA construction more commonly called allowable stress design) is a design philosophy used by civil engineers. The designer ensures that the stresses developed in a structure due to service loads do not exceed the elastic limit.
Yes fashion design is in a safe enviroment but may cause a lot of stress
limit state method
it is a method of design in rcc structures, in which stresses of materials is calculated by using working load and compared with allowable stress by considering a linear stress strain relation ship.
i think , because water tanks are more vulnerable structures and plus the tank is sometime overfilled and sometime empty, the pressure inside is so varying, its needs more safety precautions and as we all know working stress method assumes more safety factor than limit state design, which is an economical design, we prefer to use working stress method...

Voltage stress on an insulator refers to the amount of electrical stress or pressure that the insulator is subjected to due to the voltage applied across it. Excessive voltage stress can lead to insulation breakdown, resulting in electrical failures or arcing. Proper design and selection of insulators are important to ensure that they can withstand the voltage stress levels they are exposed to.
