Linear Static Analysis

STATIC ANALYSIS FEATURES

• Multiple load cases
• Linear buckling analysis
• Automatic wavefront optimization
• Interlaminar shear and edge effects for composite elements
• Restarts
• Automatic submodeling in user-defined regions for more accurate stress calculations

MATERIAL PROPERTIES

• Isotropic or orthotropic, temperature dependent
• Directional tensile, compressive, and shear failure stresses for composite elements
• Tsai-Wu coupling coefficients for composite structures

LOADING

• Point force, moment on nodes or range of nodes in local or global coordinate system
• Distributed force, pressure load
• Linear, angular acceleration
• Thermal loading
• Temperature distribution may be obtained from NISA II/HEAT TRANSFER analysis
• Specified displacement

BOUNDARY CONDITIONS

• Specified nodal displacement (zero/ non-zero; translation or rotation)
• Coupled displacement; multipoint constraints

PRINTED AND GRAPHICAL OUTPUT

• Displacements, stresses, and strains at elements and nodes
• Principle stresses and their directions
• von Mises, maximum shear, and octahedral shear stresses
• Averaged and unaveraged nodal stresses, element stresses at Gauss points and centroid
• Buckling load forms and mode shapes
