The world is nonlinear and dynamic

To accuraely simulae he srucural behavior o your designs, you need poweruladvanced analysis capabiliies, such as hose available in SolidWorks Simulaion.

Nonlinear analysis problemsNonlinear srucural analysis problems generally all wihin hree caegories:nonlinear maerials, nonlinear geomeries, and nonlinear ineracions beween pars.O course, you may ace a simulaion challenge ha involves all hree. You may beusing a hyper-elasic maerialsuch as an elasomerin a shape ha consiuesboh srucural nonlineariies, where he response varies disproporionaely o heapplied orces, and geomeric nonlineariies, where displacemens aler a srucuressiffness.

The pracical applicaions o nonlinear maerials analysis vary widely. In a nonlinearanalysis o a componen, ailure may be defined by he exen ha a maerialyields raher han i he maerials yields, as in linear analysis. You may also wano examine differen ailure modes, such as buckling, snap-hrough, oil-canningeffecs, or large displacemens. Many modern maerials, such as plasics,synheics, and composies, have unique properies ha require nonlinear maerialsanalysis o capure heir complex load response behavior. An increasing numbero producs, such as medical sens or plasic clips, are designed o deorm inshape and srech wihou ailing, behavior ha can only be undersood hrough acombinaion o nonlinear maerial and nonlinear geomery analyses.

When youre dealing wih nonlinear maerials in a flexible srucure, youll need ocombine large displacemen and nonlinear maerial analysis. An imporan

Sress siffening can eiherincrease or decrease he componens siffness depending upon he applied loadsand he componen geomery.

When he applied load is a unciono ime, and he maerial response is a uncion o displacemen or emperaure,designs can respond in ways ha are difficul o predic ye easily simulaed wihSolidWorks Simulaion.

Predicing he impac o ime-varying loads and oher load-relaed effecs, such as

Theycan also vibrae in ways ha can be airly obvious or disincly unpredicable.Vibraion can be magnified as a resul o load-ineria coupling or amplified byperiodic orces as a resul o resonance. The advanced dynamics simulaioncapabiliies in SolidWorks Simulaion enable you o solve perplexing problemsrelaed o vibraion, wheher is hrough modal, modal ime hisory (ime response),

Someimes a dynamics problem will involve a load ha is a uncion o requencyraher han ime, such as a shaker able. This is known as harmonic analysis, andis beneficial in many ypes o design, especially hose wih roaing componens.For cases where he load is no deerminisic, you can conduc a random vibraionanalysis, which akes a probabilisic approach o load definiion. You can evensimulae vibraion effecs relaed o he loads generaed by an earhquake.

Simulating the real world requires multiphysics analysis

While a large porion o simulaion problems examine a paricular ype o physical

phenomenasuch as nonlinear srucural, dynamics, fluid dynamics, and hermalanalyseshere are many siuaions ha require a combined muli-physicsapproach. Examples o muli-physics simulaions include hermal sress orhermo-mechanical (hermal/srucural), fluid srucural ineracion (flow/srucural),fluid flow wih hea ranser (flow/hermal), and fluid srucural ineracion wih hearanser (flow/hermal/srucural).

The combinaion o SolidWorks Simulaion and SolidWorks Flow Simulaionprovides you wih a powerul, inegraed suie or analyzing many possiblecombinaions o physical phenomena, so you can gain a definiive undersandingo how various physical phenomena affec he way your design will uncion andperorm.

The impact of temperature on structuresMos producs are no deployed in environmens ha mainain a single uniormemperaure, and many producs are subjeced o heaing and cooling cycles hacan affec a srucures mechanical inegriy and response. SolidWorks Simulaioncan help you analyze he impac o hea on srucural perormance.

For example, in some cases, he disribuion o hea wihin a srucure can influencehow a design will deorm, and conversely, srucural deormaion can affec heways ha hea moves hroughou a srucure. Someimes, he naure o hisineracion is primarily in one direcionhe srucural response alers hermalbehavior or hermal responses affec srucural perormance. A oher imes, heineracion is boh ways, when each ype o physical response impacs he oher.

This is an ineracive process ha ofen requires a nonlinear hermal/srucuralanalysis o simulae correcly.

For insance, you are designing a sysem in which fluid flow alers emperaure, hechanges in hea ranser cause srucural deormaion, and he deormaion changeshe boundary governing he flow, which changes he naure o he flow, whichaffecs emperaure, and he circle o inerrelaed physical responses coninues.This is a classic hermal/flow/srucural muli-physics analysis problem.

While no all engineering challenges require a hree-pronged hermal/flow/srucuralmuli-physics simulaion soluion, here are a large number ha do. By using

SolidWorks Simulaion soluions o mee your nonlinear srucural, dynamics, fluidflow, and hermal analysis needs, youll have a powerul ool in your invenory whenand i you need a muli-physics analysis soluion.

Many ypes o producs require cooling or heaing sysems or managing emperaure levels.

Wih SolidWorks Flow Simulaion, you can reduce prooyping cycles and coss by opimizing he
