You may increase the slab thickness and/or calculate the steel reinforcement required to withstand against the applied shear stress.
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.
Psychological answer:distress- negative stress - often related to issue "out of your control" - consumes your daily living. coping with iteustress- positive stress- prompts you to do what needs to be solved, accomplished or decided. manage - problem solve, deal withScience / Engineering answer:Compression, tension and shear.
Whenever an elastic body subjected to loads in its 3 dimensions, the stresses will get developed along the principal axis of the body. These are the principal stresses. These stress should not exceed the yield stress of the material. Von Mises (1913) postulated that, even though none of the principal stresses exceeds the yield stress of the material, it is possible for yielding of the same from the combination of stresses. The Von Mises criterion is a formula (refer any textbook which content failure theories for Ductile Materials) for combining these 3 stresses into an equivalent stress, which is then compared to the yield stress of the material.
Normal stress and shear stress
That is stress in three dimensions. Biaxial stress is in two dimensions. Triaxial stress has normal and shear stresses along each of three planes. Most beams can be analyzed with uniaxial stress; plates with biaxial; solids with triaxial
If a the stress of a material exceeds the yield stress, it will not be able to return to its original length or shape once the force is removed.

the material looses its shape
the material looses its shape
hehe of course the material will be deform :)
Internal stress exceeds the strength of the material. The cause of the stress is that the "leading edge" of the object stops while the "trailing edge" is still moving.
Everything causes stress my friend
Everything causes stress my friend
Yes, indeed, it is. All other stress is due.
The maximum allowable stress is that value beyond which, after applying an appropriate factor of safety its particular strength criterion is exceeded and failure occurs. For example, if aluminum strength in yield is 35,000 psi, and factor of safety is 1.25, its maximum allowable stress against yield is 35,000/1.25 = 28,000 psi
You usually say that the member fractures or fails at its ultimate stressDepending on the properties of the material, as stress increases, a typical metal will undergo elastic deformation, then a region of (nearly) constant plastic deformation, then strain hardening, a period of necking and then fracture.
