First, I pondered about the concepts of force and pressure, force cant exist without pressure, vice versa. Imagine a an adhesive sandwiched between a tabletop and a silicon wafer. (this is part 1)(adsbygoogle = window.adsbygoogle || []).push({});

Now, when you exert a shearing force F_{shear}above the adhesive and between the silicon thickness, the adhesive-silicon force exerts an adhesive force opposite in direction to the shearing force. Simultaneously, the adhesive-table force exerts an adhesive force opposite in direction to the shearing force.

This is shown as in diagram 1.

At the point of cohesive failure,

F_{shear}= F'_{si}+ F'_{table}

If F'_{si}> F'_{table},

the point of rupture would be the table-adhesive contact

If F'_{table}> F'_{si},

the point of rupture would be the silicon-adhesive contact.

Now, I know that F'_{table}is less than F_{table}, where F_{table}is the TRUE or MAXIMUM adhesive contact force between the adhesive and table.

Furthermore, I know that F'_{si}is less than F_{si}, where F_{si}is the TRUE of MAXIMUM adhesive contact force between the adhesive and silicon.
