# STRESS & STRAIN ANALYSIS

 CALCULATORS Calculator Usage Hooke's Law for General Stress - Strain Calculations Calculates stress-strain relations for a homogeneous isotropic material. Plane Stress and Transformations Calculates normal and shear stresses at a specific point for rotated coordinate system for plain stress state. Principal Stress and Maximum Shear Stress Calculator Calculates in-plane principal and maximum shear stress, the principal and maximum shear stress angle and Von Mises stress at a specific point for plane stress. Mohr's circle is also drawn according to input parameters. Mohr's Circle for 3D Stress Analysis Calculates principal stresses, maximum shear stresses and Von Mises stress for 3 dimensional stresses. Calculator can also be used to calculate out-plane stresses for plane stress state. Mohr's circle is also drawn according to input parameters. Yield Criteria for Ductile Materials Evaluates material yield condition in plane stress state using Maximum Shear Stress Theory and Distortion-Energy Theory. Thin Walled Pressure Vessel Stress Calculations Calculates principal stresses and maximum shear stress of thin-walled pressure vessel. Cylindrical and spherical vessels can be analyzed. Plane Strain and Transformations Calculates normal and shear strains at a specific point for rotated coordinate system for plain strain state. Plane Strain and Principal Strains Calculates in-plane principal and maximum shear strain, the principal strain angle. Strain Calculation With Strain Rosette Measurement Calculates normal and shear strains on a plane by using the measurement results of strain gage rosette. Plane Stress Calculation with Strain Rosette Results Calculates principal stresses of plane stress state with the usage of strain gage rosette measurement results. Modulus of Rigidity (Shear Modulus) Calculates modulus of rigidity of a material with modulus of elasticity and Poisson's ratio values. Shear Stress (Single and Double Shear) Calculates shear stress in single and double shear joints.

 EXAMPLES Example Usage Thin Walled Pressure Vessel Stress Calculation Example An example about the calculation of stresses on a pressure vessel, evaluation of yield criteria of material and stress transformation to find shear and perpendicular stresses on welding of the cylindrical body of the pressure vessel. Torsion Of Solid Shaft An example about the calculation of torsional stress on stepped shaft. After calculation of torsional stress, principal stresses are calculated and evaluation of yield criteria of material is done with these stresses. Principal Stress Calculation Example with Strain Gauge Measurement An example about the calculation of normal and shear strain and principal stresses on a machine component with the usage of strain results which have been measured with 45° Strain Gage Rosette.
